Hi,
We had hit the similar issue during below invocation:
{code:java}
try
{
bean = new WrapDynaBean(aInChildClass.newInstance());
}
catch (InstantiationException e)
{
getLogger().error(e.getMessage());
}{code}
{code:java}
priority:5 - threadId:0x00007fc6c0a4b000 - nativeId:0x270 - nativeId
(decimal):624 - state:RUNNABLE
stackTrace:
java.lang.Thread.State: RUNNABLE
at java.util.WeakHashMap.get(WeakHashMap.java:403)
at
org.apache.commons.beanutils.WrapDynaClass.createDynaClass(WrapDynaClass.java:425)
at
org.apache.commons.beanutils.WrapDynaClass.createDynaClass(WrapDynaClass.java:404)
at org.apache.commons.beanutils.WrapDynaBean.getDynaClass(WrapDynaBean.java:230)
at org.apache.commons.beanutils.WrapDynaBean.<init>(WrapDynaBean.java:79)
at org.apache.commons.beanutils.WrapDynaBean.<init>(WrapDynaBean.java:61){code}
Is there a workaround for now on this ? We are using version:
{code:java}
<version>1.9.2</version>{code}
Thank You in advance.

> 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 java.util.WeakHashMap.get(WeakHashMap.java:403)
> 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.
> I have attached the thread dump for reference.

> what is the solution for this issue?
