> Infinispan server is hanging intermittently during stop causing the build to timeout after 3h. This can be seen in the CI builds, for example:
> http://ci.infinispan.org/viewLog.html?buildId=27005&tab=buildResultsDiv&buildTypeId=Infinispan_MasterHotspotJdk8?guest=1
> http://ci.infinispan.org/viewLog.html?buildId=26651&buildTypeId=Infinispan_MasterHotspotJdk8&tab=buildResultsDiv&guest=1
> In all case the deadlock is detected:
