Jinmei Liao commented on GEODE-10092:
-------------------------------------
This exception is hard to reproduce. EntriesSet.size() ultimately calls
LocalRegion.getRegionSize(), first step is to add logging message when size
goes negative for further investigation when this error happens.
> IllegalArgumentException: Illegal Capacity (with a negative value) thrown
> from EntriesSet.toArray() in client

> Issue Type: Bug
> Reporter: Jinmei Liao
> Priority: Major
> Labels: needsTriage

> In some case, we see the following stack trace when executing
> entriesSet.toArray() call: Exception java.lang.IllegalArgumentException:
> Illegal Capacity: -40
> at java.util.ArrayList.<init>(ArrayList.java:157)
> at
> org.apache.geode.internal.cache.EntriesSet.toArray(EntriesSet.java:251)
> at
> org.apache.geode.internal.cache.EntriesSet.toArray(EntriesSet.java:245)
> looks like the entriesSet.size() call will sometimes returns a negative value.
