---------------------------------------
Summary: Old client gets null memberID in cache listener
Key: GEODE-2954
URL: https://issues.apache.org/jira/browse/GEODE-2954
Project: Geode
Issue Type: Bug
Components: regions
Reporter: Bruce Schuchardt
Fix For: 1.2.0
I was doing backward compatibility testing and found a 1.0 client was getting a
null memberID in a cache listener

Invoked util.SilenceListener for key Object_7399: afterDestroy in edge1, pid

This was in an old test suite whose testing infrastructure isn't in the Geode
repo. I'm writing a unit test to reproduce the problem.
If you look at EventID.java you can see that it catches IOExceptions in
deserializing the memberID of the event and returns null without logging the
problem.
{code}
try {
result = InternalDistributedMember.readEssentialData(dis);
} catch (IOException e) {
// nothing can be done about this
} catch (ClassNotFoundException e) {
// ditto
}
{code}
