Description
If during concurrent classloading process LinkageError exception is caught and then rethrown, future classloading process will fail whether it is possible to recover or not. Mainly, badly behaved classloaders are prone to this issue.

Hotspot and IBM v.5.0b VMs are affected by this issue.
IBM VM v.1.4.2 is not affected.
