> WindowsUnitTestOpenJDK8 passing here:
> https://concourse.apachegeode-ci.info/teams/main/pipelines/apache-develop-main/jobs/WindowsUnitTestOpenJDK11/builds/258
> Has NPEs like this in the logs:
> {code}
> Exception in thread "BatchRemovalThread for GatewaySender_sender_4" > Task
> :geode-wan:test
> java.lang.NullPointerException
> at
> org.apache.geode.internal.cache.wan.parallel.ParallelGatewaySenderQueue$BatchRemovalThread.checkCancelled(ParallelGatewaySenderQueue.java:1780)
> at
> org.apache.geode.internal.cache.wan.parallel.ParallelGatewaySenderQueue$BatchRemovalThread.run(ParallelGatewaySenderQueue.java:1879)
> {code}
> It appears that in
> {{ParallelGatewaySenderQueue.BatchRemovalThread.checkCancelled()}} in the
> expression on this line:
> {code}
> if (cache.getCancelCriterion().isCancelInProgress()) {
> {code}
> Somehow either {{cache}} is null or {{cache.getCancelCriterion()}} is null.
> The latter seems impossible since that cancel criterion is a {{final}}
> reference initialized at the point of declaration.
