Istvan Toth updated HBASE-29234:
--------------------------------
Description:
This is from the Hadoop test suite, but the problem is in HBase
{noformat}
[ERROR]

java.lang.reflect.InaccessibleObjectException: Unable to make private native

{noformat}
Due to JEP416, we are no longer able to set the LocationsOrderInterceptor on
JDK18+.
While the code is supposed to catch these instances and still work (just not
optimally), it does not catch InaccessibleObjectException.
Catching InaccessibleObjectException is not real fix, but it allows for running
with JDK18+.
The real fix would either be avoiding reflection for this (which probably
requires Hadoop support), or using the sanity-draining workaround for JEP416
which floats around on stackoverflow.
