Attempting to use Eclipse 3.5M5 against a previous workspace and I'm receiving an AssertionFailedException related to the resolution of Java classpath entries. I've also attemped to import the project into a clean workspace and receive the same error. In the method, JavaProject#addToResult(IClasspathEntry rawEntry, IClasspathEntry resolvedEntry, ResolvedClasspath result, LinkedHashSet resolvedEntries, ExternalFoldersManager externalFoldersManager) The curious values are: JavaProject=EnrollmentSupport (not open) rawEntry=/EnrollmentSupport/lib/jaxb-xjc.jar[CPE_LIBRARY][K_BINARY][isExported:false] resolvedEntry=/[CPE_LIBRARY][K_BINARY][isExported:false] The resolved entry in this case doesn't make any sense at all. The stack trace follows: Daemon Thread [Thread-0] (Suspended (exception AssertionFailedException)) Assert.isNotNull(Object, String) line: 85 Assert.isNotNull(Object) line: 73 Path.initialize(String,

I should add that I have an installation and can collect more information if it helps. I just wasn't sure what might be useful.
This was ugly before but with the fix for bug 336046 this can result in JDT Core not even starting up and hence also JDT UI not being able to start. Test Case (3.7 M7): 1. start fresh workspace 2. create Java project 'P' 3. change the source attachment of 'rt.jar' to "C:" ==> you'll get tons of errors 4. try to expand some of the JARs ==> you'll get tons of errors 5. exit 6. start ==> Package Explorer (whole JDT UI) doesn't load
Created attachment 194566 [details] Fix
Markus, can you +1 this as second committer besides Olivier?
(In reply to comment #4) > Markus, can you +1 this as second committer besides Olivier? Actually that's not needed as the rules don't require the committer to be from the same component. +1 for RC1.
Looks good. I'll commit today.
Olivier, I think this would be a good one for 3.6.2+.
Even if bug 336046 was not released for 3.6.2+, we can still release that fix for 3.6.2+.
Released in BETA_JAVA7, HEAD and 3_6_maintenance with a regression test.
Verified for 3.7 in I20110505-0800.
Verified for 3.7RC1 using build I20110511-0800.
