RFR: 8343529: serviceability/sa/ClhsdbWhere.java fails AssertionFailure: Corrupted constant pool

[Chris Plummer]

These two tests both do stack dumps with one or more active threads. This can result in SA throwing an exception if the thread is in a bad state. However, SA will still generate stack traces for all other threads, and the tests should still pass all the output checks, so we can safely ignore these exceptions and not fail the test as a result of them.

Tested by running all SA tests 50 times on all supported platforms. Tier1 testing in progress.
