This is a dup of bug 181327. Please try on the M7 build which should be final today. *** This bug has been marked as a duplicate of bug 181327 *** |
Build ID: 3.3 M6 Steps To Reproduce: 1. Delete ${workspace_loc}/.metadata/.plugins/org.eclipse.pde.core/122332434215.workspace/.extensions 2. Launch Eclipse 3. Close Eclipse 4. Attempt to launch Eclipse again More information: I can reproduce it consistently. Essentially, the .extensions file that PDE writes as I close Eclipse seems to be corrupt and I cannot restart Eclipse on my workspace unless I delete that file. When I run with tracing on, the last entries I see before it hangs are: ->started update@plugins/org.eclipse.pde_3.3.0.v20070320-0010.jar [89] ->started update@plugins/org.eclipse.pde.core_3.3.0.v20070323-1600.jar [91] Time to read extensions: 30 ms Time to read extensions: 10 ms By debugging, I found that the (seemingly) infinite loop is in org.eclipse.osgi.internal.module.ResolverImpl.findBestCombination(ResolverBundle[] bundles, ResolverConstraint[] multipleSuppliers, int[] bestCombination) The full stack trace is: Thread [main]
