[jira] [Comment Edited] (BEANUTILS-509) WeakHashmap enters into
infinite loop in WrapDynaClass.java
[ https://issues.apache.org/jira/browse/BEANUTILS-509?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16649046#comment-16649046 ]

------------------------------------------------------------------
For now, I can see that wrapping the weak map into a synchronized map may help but this causes the build to fail, not because any unit tests fail, but because the Maven Surefire plugin that runs the tests blows up:

There is obviously something stuck, hanging or crashing.
[~akshaygehi] or anyone: Can you reproduce this?
My attached patch updates Surefire and Jacoco to their respective current versions, to no avail. Note the attached dump files and the one containing {{java.lang.OutOfMemoryError}}.
Thank you,

> We noticed that our application was using too much of CPU , all the 6 cores were used.
> On capturing the thread dump we saw that large number of threads were in the running state and in :

> at org.apache.commons.beanutils.WrapDynaClass.createDynaClass(WrapDynaClass.java:425)

> So we are suspecting that the thread has entered into indefinite while loop and hogging all the CPU resources.
