Jianxia Chen commented on GEODE-9583:
-------------------------------------
The NotSerializableException is reported on vm2, where the
LongWrapperSerializer is explicitly registered before connecting to distributed
system and all region operations. So it is expected that on vm2, when
FlusherThread writes LongWrapper to the disk, the LongWrapperSerializer should
have already been registered. It is still unclear why NotSerializableException
is thrown. I suspect that other tests in the same file does not clean the test
environment completely after finish, and leaving some data in vm2 to write to
disk before the serializer is registered. But initial test does not support
this assumption.
