To repro. 1. open a workspace with the APT plugin as a project 2. right-click org.eclipse.jdt.core.tests.RunModelTests in the package explorer 3. select Run-as Junit plugin test. (make sure you are running under a 1.5 VM) You will see the following exception. We need to figure out what is going on java.lang.IllegalArgumentException: Attempted to beginRule: R/, does not match outer scope rule: L/JavaSearch/src/wc/X.java at

I think that the fix here may be updating ReconcileWorkingCopyOperation.isReadOnly() to return false. This should schedule the operation with the workspace as the scehduleing rule. Need to verify this will work & need to run it by the JDT team.
Should now be fixed since reconcile type-generation only works on in-memory copies, and doesn't touch disk, doesn't take any locks, and doesn't schedule itself with an ISchedulingRule.
