Description Don Nelson

I occasionally get this error when starting eclipse.  I normally start with the
-clean option.  Running on jdk 1.7.0_09 x64.  The details from the log:

!ENTRY org.eclipse.ui.workbench 4 2 2012-11-16 08:05:02.981

I have no clue what's going on here.

Can you tell me what build you are using and whether you have any additional plug-ins installed?

Comment 2 Jay Arthanareeswaran

ObjectVector is in the same bundle as the other ones in the stack. Unlikely that there will be a problem loading that class. Is there any other class by the same name in any of the other plug-ins?

Comment 3 Stephan Herrmann

Don, could you please paste the exact version of org.eclipse.jdt.core inside the plugins folder of your Eclipse install? TIA.

I'm not sure if any of the byte code weaving technologies (as used in tools like AJDT, Scala IDE, OTDT) could possibly create this symptom, do you have any of these installed?

If we don't find a hint along these paths, we might need help from Equinox to find out how this problem can ever be possible.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're closing this bug.

If you have further information on the current state of the bug, please add it and reopen this bug. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
