Could not find the steps to reproduce but the snapshot shows something is wrong. The MultiFixResolution is being shown as part or ArrayList. Attaching the erroneous class and snapshot.

Sorry folks. The real culprit was Mylyn. Forwarding it to them. No content assist is better than wrong content assist.
Ankur, could you provide more detail why you believe this error was caused by Mylyn? Does the behavior change if you activate/deactivate a task? What happens if you disable the Task-Focused content assist in the preferences?
(In reply to comment #4) > Ankur, could you provide more detail why you believe this error was caused by > Mylyn? I didn't thought of Mylyn first hand. And my first guess was JDT UI. They hinted me it could be due to Mylyn. So this is what I tried. I opened the same workspace with an eclipse instance without Mylyn and I did not see the problem. I then opened a new workspace with same workspace using Eclipse SDK with Mylyn. The problem appeared after I did a F3 on the class that is being shown here. Before this I had opened Task List view to ensure no task was active. > Does the behavior change if you activate/deactivate a task? No task was active. > What happens > if you disable the Task-Focused content assist in the preferences? problem persists even after disabling them It is reproducible though if you check out o.e.pde.ui and replace the ResolutionGenerator.java (attached). I tried to reproduce with simpler case but could not. However I did encountered this exception once eclipse.buildId=I20100603-1500 java.fullversion=J2RE 1.5.0 IBM J9 2.3 Windows XP x86-32 j9vmwi3223ifx-20080811 (JIT enabled) J9VM - 20080809_21892_lHdSMr JIT - 20080620_1845_r8 GC - 200806_19 BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=en_US Command-line arguments: -os win32 -ws win32 -arch x86 Warning Tue Jun 22 00:37:14 IST 2010 The 'org.eclipse.mylyn.java.ui.javaAllCompletionProposalComputer' proposal computer from the 'org.eclipse.mylyn.java.ui' plug-in did not complete normally. The extension took too long to return from the 'computeCompletionProposals()' operation.
Thanks for the details. We'll try to reproduce it.
I wonder if this is the same issue as bug 461809, that the Java proposal computer doesn't work correctly when it runs after other proposal computers.
