Spring v3.0.2 Learning Note 16 (Cont.)- Resolve NullPointerException on weblogic v10.3

In this article http://wangxiangblog.blogspot.com/2010/10/spring-v302-learning-note-16-integrate.html, I mentioned that NullPointerException occured if deployed hessian project to weblogic v10.3

After seach oracle website, found the info as follows
---------------------------------------------------------------------------------------------------
After some research on the stack trace, I found the reason for this error is Hession Spring servlet closes the input stream explicitly. While when WLS' reclaiming the connection for reuse(keep-alive) purpose, it tries to read the input stream to clear unread chunks. NPE happens here as input stream has been closed.

There is an existing bug on this: Bug 8183755. Patches are available for bug  8183755:
