[infinispan-issues] [JBoss JIRA] (ISPN-2538) Endless loop in TreeMap.remove at shutdown of query-enabled cache

[Marko Lukša (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-2538?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12736617#comment-12736617 ] 

Marko Lukša commented on ISPN-2538:
-----------------------------------

This is probably not only a Infinispan-query problem, but a more general one. 

The bug happens when Capedwarf shuts down a cache at the same time as {{EmbeddedCacheManager}} is shutting down the same cache.    The fix is to synchronize on the EmbeddedCacheManager instance whenever you are manually shutting down the cache. 

Not sure whether Infinispan should handle this or not.
