Pavel Rebriy commented on HARMONY-5532:
---------------------------------------

There are several bugs in SerializableClassesTest test. First of all it fails due to incorrect
deserialization with NPE:

remove locate data, delegate related classes to ICU
------------------------------------------------------------------------

With this error test returns 105 - failure status - instead of 104 - success.

Test hangs happen due to assertions in VM code. I see at least 2 assertion: in kernel classes
and in GC. I'm going to evaluate these assertions more closely.
