Created attachment 89764 [details] screen shots of error popup and error log Build ID: M20071023-1652 Steps To Reproduce: 1. Edit any Java file (UI: actionClass, actionForm, or seam: SLB, SFB, entity) 2. Add the following in any method that your UI will call: Long NPE = null; if (NPE.longValue() == 0); //this will throw a NullPointerException 3. Start your server 4. Execute your UI that will execute the NPE mentioned above 5. In your Eclipse Console window, you will get a stack trace. Click on the error that is represented by the NullPoingerException (i.e. your java file/class). 6. You will get the following error displayed in eclipse, and the file will not be opened in eclipse: Class file name must end with .class More information: 1. The .errorlog file has the following information: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ java.lang.IllegalArgumentException: Class file name must end with .class at org.eclipse.jdt.internal.core.PackageFragment.getClassFile(PackageFragment.java:188) at org.eclipse.jdt.internal.core.util.HandleFactory.createOpenable(HandleFactory.java:116) at org.eclipse.jdt.internal.core.search.matching.MatchLocator.locateMatches(MatchLocator.java:1163) at org.eclipse.jdt.internal.core.search.JavaSearchParticipant.locateMatches(JavaSearchParticipant.java:94) at org.eclipse.jdt.internal.core.search.BasicSearchEngine.findMatches(BasicSearchEngine.java:217) at org.eclipse.jdt.internal.core.search.BasicSearchEngine.search(BasicSearchEngine.java:502) at org.eclipse.jdt.core.search.SearchEngine.search(SearchEngine.java:550) at org.eclipse.jdt.internal.debug.ui.actions.OpenTypeAction.findTypes(OpenTypeAction.java:164) at org.eclipse.jdt.internal.debug.ui.actions.OpenTypeAction.findTypeInWorkspace(OpenTypeAction.java:143) at org.eclipse.jdt.internal.debug.ui.console.JavaStackTraceHyperlink$1.run(JavaStackTraceHyperlink.java:106) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 2. Here is a copy of our .eclipseini file: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -showsplash com.genuitec.myeclipse.product --launcher.XXMaxPermSize 256m -vmargs -Xms128m -Xmx512m -Duser.language=en -XX:PermSize=128M -XX:MaxPermSize=256M ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 3. We start eclipse using jre 1.6.04 4. Our eclipse is configured touse jdk 1.6.04 as the compiler. 5. We use JBoss 4.2.2 for our server deployment 6. The only plug-in we use is MyEclipse (myeclipseide.com)
It looks like this is related to if your project names have periods in them. I renamed our projects from: enterprise.ear to enterprise-app enterprise.war to enterprise-web enterprise.ejb.jar to enterprise-ejb and that worked! I guess having periods in the names was the cause of this. Hopefully this will help with the fix. :-) Anthony
I am seeing this issue too and it appeared all of a sudden today. I have not made any chnages to my eclipse environment... like adding or removing a plugin. It happens when: 1. I do a search - even a File search 2. If I try to refactor code like renaming a unit. However if I uncheck "update project references" on Rename Compilation Unit dialog, it gives this same error but is able t recover from it and allows renaming the class. Note: I dont have any dots in the project name Here are the traces: eclipse.buildId=I20080617-2000 java.version=1.5.0_16 java.vendor=Sun Microsystems Inc.

Well I have fixed my IDE. IN mid of December I had added a plugin for supporting Harvest Configuration Management tool. I rolled it back and now I can: 1. Rename compilation units with "update project references" checked. 2. Java Search The Harvest Eclipse plugin can be found here... I am not sure which version I used: http://supportconnectw.ca.com/public/harvesteclipse/
I have been unable to reproduce this problem (using 3.5 RC4). Eclispe projects also contain periods, and I am able to follow links for exception names from stack traces. Please re-open if this continues to be a problem.
