LineReader Bug (Open or Close Parenthesis)

[irinaleo]

Hi,

I have an interactive shell using picocli-shell-jline3 as in this example.

When I run the example and type in an open or closed parenthesis, I get a Null Pointer Exception. Here is the stack trace coming from my main method when I read in the line: line = reader.readLine(prompt, rightPrompt, (MaskingCallback) null, null)

java.lang.NullPointerException at org.jline.console.impl.SystemRegistryImpl.commandDescription(SystemRegistryImpl.java:405) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:566) at org.codehaus.groovy.reflection.CachedMethod.invoke(CachedMethod.java:107) at groovy.lang.MetaMethod.doMethodInvoke(MetaMethod.java:323) at groovy.lang.MetaClassImpl.invokeMethod(MetaClassImpl.java:1268) at groovy.lang.MetaClassImpl.invokeMethodClosure(MetaClassImpl.java:1048) at groovy.lang.MetaClassImpl.invokeMethod(MetaClassImpl.java:1142) at groovy.lang.MetaClassImpl.invokeMethod(MetaClassImpl.java:1035) at groovy.lang.Closure.call(Closure.java:412) at org.codehaus.groovy.runtime.ConvertedClosure.invokeCustom(ConvertedClosure.java:50) at org.codehaus.groovy.runtime.ConversionHandler.invoke(ConversionHandler.java:110) at com.sun.proxy.$Proxy20.apply(Unknown Source) at org.jline.widget.TailTipWidgets$CommandDescriptions.evaluateCommandLine(TailTipWidgets.java:737) at org.jline.widget.TailTipWidgets$CommandDescriptions.evaluateCommandLine(TailTipWidgets.java:689) at org.jline.widget.TailTipWidgets.doTailTip(TailTipWidgets.java:262) at org.jline.widget.TailTipWidgets.tailtipInsert(TailTipWidgets.java:249) at org.jline.widget.Widgets$1.apply(Widgets.java:69) at org.jline.reader.impl.LineReaderImpl.readLine(LineReaderImpl.java:689) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:566) at org.codehaus.groovy.runtime.callsite.PlainObjectMetaMethodSite.doInvoke(PlainObjectMetaMethodSite.java:43) at org.codehaus.groovy.runtime.callsite.PojoMetaMethodSite$PojoCachedMethodSite.invoke(PojoMetaMethodSite.java:191) at org.codehaus.groovy.runtime.callsite.PojoMetaMethodSite.call(PojoMetaMethodSite.java:56) at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:47) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:125) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:166)

Is this a known bug?
