IllegalArgumentException

Hi,
Sometimes we get an error like following in the wlsdm logs. What could be the reason?

Hi,
This exception throws from JFR and Apache BCEL. It can be WebLogic/JRockit/Java defect while using Apache BCEL.
By the way, do you have any additional agent on this managed server except wlsdm_agent?
We will reproduce this case and get back to you as soon as possible.
