Reproducible: Always

Steps to Reproduce:
According to the error log:
1. Experience a workspace crash
2. Get assorted errors including "Unhandled event loop exception" and "An internal error occurred during: "Initialize Java Debug Options"."
3. Then get the error reported in Details and never be able to use breakpoints again.

I have searched exhaustively to try and find the file containing the offending string... to no avail.

Problems with setting Java breakpoints goes to the Debug team.

Comment 2 Darin Wright

Looks like a method breakpoint is causing trouble. You might try to delete the .markers file from the associated projects directory in the ".metadata/.plugins/.org.eclipse.core.resources/.projects" directory of your workspace. (If you know what project(s) you have method breakpoints in).

Comment 3 Darin Wright

However, we should be catching the PatternSyntaxException to avoid this, and throwing a CoreException, which will be caught and handled by the framework. The framework should probably delete the markers for which breakpoints could not be re-created.

Deleting the .markers file does seem to have restored my breakpoint capabilities!!  Thanks!!

Please review, Mike.

Comment 7 Michael Rennie

Patch looks good. Applied to HEAD

To reproduce the exception:

1. create a method breakpoint
2. export it
3. edit the *.bkpt replacing a '.' with a '\'
4. try to import the *.bkpt file

happens:
