Subject [jira] [Commented] (POOL-230) waiting on <0x00000000e7440168> (a org.apache.commons.pool.impl.GenericObjectPool$Latch)

    [ https://issues.apache.org/jira/browse/POOL-230?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13461912#comment-13461912
] 

Phil Steitz commented on POOL-230:
----------------------------------

Looks like normal behavior to me when the pool is configured to block when exhausted and there
are no instances available in the pool.  The thread is executing a timed wait, waiting for
an instance to become available.  This does not look related to POOL-149 to me.
