The distributedTest hangs are once again caused by deserialization
problems in a query message class. The deserialization errors are
caused by the fix for GEODE-4822
<https://issues.apache.org/jira/browse/GEODE-4822>, which I am going to
revert this morning. We obviously don't have the test coverage to
ensure that this fix doesn't cause problems and I don't want to keep
finding new and unusual hangs.
Details, if you have the time:
The hang occurred because someone checked in a new
query/indexing/pdx-read-serialized test at the same time I checked in a
fix for a different hang. The message class that I modified turns out
to have a field that sometimes holds an internal Geode object and other
times holds a user object. In the former case we want to protect
against it having been PDX serialized by ignoring pdx-read-serialized.
In the latter case we want to respect the user's pdx-read-serialized
setting. There's no straightforward way of knowing which kind of object
it is, internal or external, before deserializing it.
