Jianxia Chen commented on GEODE-9532:
-------------------------------------
This bug is not easy to reproduce. Based on the analysis with additional
logging, this is more like a test issue. VM2 disconnected and registered a
customized DataSerializer before reconnect. Then VM2 did a put and get on a
persistent replicated region. When the asynchronous disk store were trying to
flush the data to disk on the other two VMs VM0 and VM1, these two VMs were not
aware of the new customized DataSerializer, therefore they throw serialization
exception when serializing the instance of LongWrapper class. It depends on
timing. Most of the time, when the async disk store is flushing, VM0 and VM1
have already got the customized DataSerializer after VM2 reconnects, so there
is no serialization issue and the test passes.
