Summary

0003777: npe on second hessian call (hessian flex)

Description

(rep by Riccardo Cohen)

I have converted my tutorial
http://architectedulogiciel.fr/tutorials/resinutf8flex.php [^] to resin
4.0.1 with hessian flex library 4.0.0
When the flex client sends an object (a very simple one) to the server,
the first time it works, but the second time I have an error :

  java.lang.NullPointerException
  at com.caucho.hessian.io.Hessian2Input.readObject(Hessian2Input.java:1609)

  at com.caucho.util.ThreadPool$PoolThread.runTasks(ThreadPool.java:874)
  at com.caucho.util.ThreadPool$PoolThread.run(ThreadPool.java:787)

If I change only the flex library and put hessian-flex-3_1-snap.swc =>
it works back again. You'll find the source code here :

Notes
(0004338) ferg 12-16-09 11:26	The NPE has been fixed on the server side, but the problem is in the client. The client needs to clear the class references for the next call.
