Can someone have a look ? It's really easy to reproduce .. thanks |
|
Please make the example complete, the "Aspect" annotation is missing. Or even better, attach the simple project with the used compiler settings. |

Thanks! I do get three different exceptions trying code completion on anything inside the "fetch" block below @jjohnstn : it could be JDT UI issue, could you please check. Errors from latest 4.30 build I20231004-1800: |
|
@jjohnstn do you have found something ? |
|
@c-koell @iloveeclipse Sorry for the delay. Doing some debugging, I do not see this is as a JDT UI issue. The problem occurs because the Constants.Group1.val1 + "." becomes a BinaryExpression with the left-side being a CompletionOnQualifiedNameReference and it has a MemberTypeBinding that has the Binding.FIELD bit set on so QualifiedNameReference.computeConversion() tries to cast it to a FieldBinding which fails. Looking at 2023-06, I see a difference in CompilationOnQualifiedNameReference.resolveType() which used to throw a new CompletionNodeFound() and after commit 32961cf returns a new CompletionNodeFound().throwOrDeferAndReturn() The throw caused it to skip the code that ends up doing the QualifiedNameReference.computeConversion() and it ended up in the finally clause in SourceTypeBinding.initAnnotationTagBits() |
|
@jjohnstn thanks for your info. Is there a plan to fix it ? |
|
@stephan-herrmann Could you take a look? I am not sure if the answer is to simply throw the old CompletionNodeFound(). |

* configure default output.. = bin/ * JavaSearchScope: improve encloses() performance #474 * [test] remove outdated latestBREE project * fix some ecj markers Especially after moving files to compiler.batch - which has no resource warnings - the @SuppressWarnings("resource") is not used - leading to a marker * Single async "Synchronizing projects" Job #419 Scheduling multiple times "while the job is running, the job will still only be rescheduled once" (javadoc) so there will be always only a single job running. Using a Set prevents touching projects multiple times. #419 Manually tested by changing Compiler Building options "Circular dependencies", which triggers a new build. * [test] fix AbstractJavaModelTests #1333 avoid asynchronous refresh. Implementation taken from org.eclipse.core.tests.resources.refresh.RefreshProviderTest.joinAutoRefreshJobs() #1333 * TestVerifier: never wait 100ms improve test time, accurate timeout * [performance] ClassFileReader: use already open Zip File instead of creating new ZipFile instance. also: * use Files.readAllBytes * removed unused code * faster toUri avoiding isDirectory() check for the JARs which are known to be no directory improves performance of read() on windows by factor 2 tested with java reference search to java.lang.Object * Stop skipping compare-with-baseline for jdt.annotation v2 One less thing that has to be manually tracked and done. * Version bump for jdt.annotation Pointed by https://download.eclipse.org/eclipse/downloads/drops4/I20231130-0020/buildlogs/reporeports/reports/versionChecks.html * Fix github urls in NOTICE file * Use try-with-resource and enable warning if not org.eclipse.jdt.core.compiler.problem.explicitlyClosedAutoCloseable=warning StringWriter does not need flush() or close() and can not throw IOException. Tests excluded. To get rid of boiler plate code. * version bumps * [21] JEP 430 String Templates (#1513) Grammar, compiler AST, resolution and code generation changes * Javadoc: fix unclosed <code> * break from loop within labeled block causes loss of nullness info (#1660) fixes #1659 * Fixes incorrect Javadoc after StringBuffer to StringBuilder change * NPE in ASTRewriteFlattener as return value of GuardedPattern.getPattern() is null (#1647) NPE in ASTRewriteFlattener as return value of GuardedPattern.getPattern() is null * Adding pomless build to JDT core This enables pomless builds for JDT coreand removes the simple pom files. Future commits can reduce the usage of pom files further. This might require enhancements in pomless builds to specify the test classes and suites eclipse-tycho/tycho#3105 * Using Simplify lambda expression and method reference syntax cleanup on core Using the JDT UI "Simplify lambda expression and method reference syntax" clean-up on jdt.core. * Internal compiler error: ArrayIndexOutOfBoundsException in latest i build (#1664) fixes #1661 * Using Simplify lambda expression and method reference syntax cleanup on all plug-ins except core Using the JDT UI "Simplify lambda expression and method reference syntax" clean-up on all plug-ins except jdt.core. * Using short-circuit in IncrementalImageBuilder * Re-normalize line-endings in git of all files to Linux style ("\n") Some files were checked-in into git having windows style line endings (\r\n). This is in general not wanted because it can cause modified files without any difference in git-staging on Windows if auto-crlf is enabled. To re-normalize line endings of all files use the following command (including dot): git add --renormalize . * Bump bundle dependencies to trigger a rebuild / fix SDK build error The change in bytecode of FullSourceWorkspaceBuildTests is due the constant value change of o.e.jdt.internal.compiler.parser.TerminalTokens.TokenNameEOF coming from #1513. Fixes eclipse-platform/eclipse.platform.releng.aggregator#1617 * False positive "Dead code" compiler error reported on org.eclipse.pde.internal.core.util.PDEJavaHelper.getExternalPackageFragment(String, String) (#1671) fixes #1667 * Use diamond operator in jdt.core repo Using the JDT UI clean-up, this removes the redundant type information. Also activating org.eclipse.jdt.core.compiler.problem.redundantSpecificationOfTypeArguments=warning The rest of the changes in the prefs file were done by the tooling, not by selecting anther value. * Improve constructor completions inside method invocations Fix #1587 (#1588) * Try-with-resource clean-up in JDT core Using the JDT UI try-with-resource clean-up on core. Also manually inlining the declaration of multiple places into the try() clause. * Make inner classes static where possible in JDT core Running the JDT performnace clean-up "Make inner classes static where possible" in JDT core * Use Use lazy logical operator (&& and ||) Running the performance clean-up "Use lazy logical operator (&& and ||)" on JDT core * Using Integer.toString directly in Disassembler It is also a JDT UI performance clean-up but this clean-up found only one occurrence. * use Path.of() to avoid 'Potential resource leak' warnings * @NonNullByDefault does not work for type arguments of a local type (#1694) fixes #1693 * ClassCastException during code completion on Annotation (#1696) fixes #1440 Also fixes noise from #1662 * CompilationUnitResolver: Name the CU that causes Exception (#1690) for example during Cleanup eclipse-jdt/eclipse.jdt.ui#950 Co-authored-by: Jörg Kubitz <jkubitz-eclipse@gmx.de> * Code selection support for String template expressions (#1699) Fixes #1685 * Report error if string template is used without preview option enabled (#1697) Improves the fix for #544 * ECJ crashes when an embedded expression contains broken code (#1702) Set haltOnSyntaxError when parsing for embedded expressions.

We have a Class where we define some static final Strings
We use this on a custom Annotation.
The fetch Attribute can take a String[].
The Exception only occurs if we try to concat more Constants.
This example works fine
With Eclipse 4.28 the code completion works fine in the fetch attrribute.
With Eclipse 4.29 we get following exception
