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:0x7fc6c0a4b000 - 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.(WrapDynaBean.java:79)
at org.apache.commons.beanutils.WrapDynaBean.(WrapDynaBean.java:61){code}
Is there a workaround for now on this ? We are using version:
{code:java}
1.9.2{code}
[~akshaygehi] Can you please let know how to pass the cache instance? should we
just create one instance of it and use ?
Thank You in advance.

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:
