We are following up for Java update with provider, we are facing difficulty
because websphere uses it's supplement Java, not open JDK.
Additional observation from thread dump is that, the issue occurs only while
calling *doEndTag()* method of Jsp class file under high load condition.

Yes, we are following up with provider in parallel, just wondering why it
always get blocked on the same line while calling *doEndTag()*, is there any
possibility of issue from application side. It comes randomly on any JSP and on
any field but on the same line, while calling *doEndTag()*. This is a common
pattern observed.

We are following up for Java update with IBM, we are facing difficulty because
websphere uses it's supplement Java, not open JDK.
Additional observation from thread dump is that, the issue occurs only while
calling *doEndTag()* method of Jsp class file under high load condition.
