isFatal
boolean isFatal
When running in the RVM, typically optimizing compiler
exceptions are caught, optionally a message is printed, and we
fallback to using the baseline compiler. However, this
may not be desirable when running regression testing because
an optimizing compiler exception may be a symptom of a serious failure.
Thus, the code throwing the exception can use an optional boolean value
to indicate if the exception is "normal" or if it should be treated
as a fatal failure for the purpose of regression testing.
