ex03t001 test: Expected ClassUnload event was not received

The following test started failing on the 03.02 nightly:

nsk/jvmti/scenarios/extension/EX03/ex03t001

It fails on x86 platforms with -client -Xcomp -Xshare:on . If run with -Xshare:off or -Xmixed it doesn't fail. The test expects ex03t001a and ex03t001b to be unloaded but ex03t001a is not being unloaded. Here is a sample log:
