-----------------------------------

             Summary: hotrod-client tests hang on Windows
                 Key: ISPN-10185
                 URL: https://issues.jboss.org/browse/ISPN-10185
             Project: Infinispan
          Issue Type: Bug
          Components: Test Suite - Server
    Affects Versions: 9.4.13.Final
            Reporter: Dan Berindei
             Fix For: 10.0.0.Beta4


All the {{ForkJoin.commonPool}} in the thread dump are busy doing blocking operations:

"ForkJoinPool.commonPool-worker-1" #66 prio=0 tid=0x42 nid=NA timed_waiting
   java.lang.Thread.State: TIMED_WAITING

{{ForkJoinPool.commonPool}} is supposed to add new threads to maintain the default parallelism level (= number of cpus), but that doesn't seem to work because {{RemoteCacheManagerTest}} is trying to start a cache and it didn't get a {{commonPool}} thread:

"testng-RemoteCacheManagerTest" #61 prio=0 tid=0x3d nid=NA waiting
   java.lang.Thread.State: WAITING
	at sun.misc.Unsafe.park(Native Method)

	at org.infinispan.client.hotrod.RemoteCacheManagerTest.testStartStopAsync(RemoteCacheManagerTest.java:55)

Server threads are all free. The first test to time out was {{ProtobufRemoteIteratorIndexingTest}}, but most put operations on {{ForkJoinPool.commonPool}} are issued by {{}}:
