Can someone who has been working on GatewaySender please take a look at this NPE?
It didn't cause any test failures, but it does show up in the output of my unit-test-openjdk11 task for one of my PRs: https://concourse.apachegeode-ci.info/builds/53189 > Task :extensions:geode-modules-tomcat8:testClasses *> Task :geode-web:testException in thread "BatchRemovalThread for GatewaySender_sender_2" java.lang.NullPointerException at org.apache.geode.internal.cache.wan.parallel.ParallelGatewaySenderQueue$BatchRemovalThread.checkCancelled(ParallelGatewaySenderQueue.java:1835) at org.apache.geode.internal.cache.wan.parallel.ParallelGatewaySenderQueue$BatchRemovalThread.run(ParallelGatewaySenderQueue.java:1936)*> Task :extensions:geode-modules-tomcat9:compileTestJava > Task :extensions:geode-modules-tomcat9:testClasses Thanks, Kirk
