Coverage tool: no longer finds class file within jar.

[wknorr]

Summary
I get the following error when trying to get coverage information for a test application when the classes are in a jar file when using jmockit-coverage 1.19:

JMockit: No classes were instrumented for coverage; please make sure that classes selected for coverage through the regular expression "com.qhrtech.emr.qa.*" are available from the runtime classpath, and that they have been compiled with debug information.

The information is correctly generated when I use jmockit-coverage 1.16 or other earlier versions.
It is also correctly generated if I have the class files outside the jar.

The application simply prints a message and waits for the user to press enter.

Steps to reproduce:

1. Compile the project: "mvn install".
2. Run the application from the command line with the following command:
   "C:\Program Files\Java\jdk1.8.0_60\bin\java.exe" -classpath ./target/TestApp-1.0-SNAPSHOT.jar -javaagent:./target/runtimejars/jmockit-coverage.jar -Dcoverage-outputDir=./CodeCoverageReports -Dcoverage-classes=com.qhrtech.emr.qa.* -Dcoverage-metrics=line -Dcoverage-output=html-nocp com.qhrtech.emr.qa.testapp.TestApp
3. While the application is waiting for the user, attempt to generate code coverage information:

• Open jconsole.
• Connect to com.qhrtech.emr.testapp.TestApp .
• Go to the MBeans tab.
• Select JMockit Coverage->Coverage Control->Operations->generateOutput.
• Click the generateOutput button.
  Results
  In the command window, the "No classes instrumented..." message is printed.

No output files are created in the output directory, CodeCoverageReports.

Versions
jmockit-coverage: 1.19 (from the Maven central repository)
Maven: 3.3.3

        System.out.println( "Press enter." );
        Scanner keyboard = new Scanner( System.in );
        keyboard.nextLine();

    }

Thanks for working on this.

I updated my pom file to bring in jmockit-coverage version 1.20 from the Maven Central Repository, which looks like it has your fix, but I still get the same error.

A bug related to classes from jars was fixed, but there was another one. Issue #229 was open for it now.
