-------------------------------------
FTR, this bug sometimes bites in Jenkins:

> WeakHashmap enters into infinite loop in WrapDynaClass.java

> 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?
