Description

If the "create region" command is executed while the Geode server is restarting it will fail with NullPointerException on that server.

It happens for persistent regions as it tries to findDiskStore but in that method, it first tries to get PdxRegistry from the cache and create a persistent Region on that. But in that case, when the cache is creating(it takes some more time if the server is restarting), if the command is executed fast it happened that creating cache is not finished and pdxRegistry is null, so every method executed on that will throw NullPointerException.

gfsh>create region --name=/test_region2 --type=PARTITION_REDUNDANT_PERSISTENT --total-num-buckets=113 --disk-store=dataDiskStore --enable-synchronous-disk=false
