A DESCRIPTION OF THE PROBLEM :
Under certain (unknown) circumstances a stack overflow will occur in the CORBA code base:
Caused by: java.lang.StackOverflowError
        at java.security.AccessController.doPrivileged(Native Method)
        at java.net.Socket.getOutputStream(Socket.java:836)
        at com.sun.corba.se.impl.transport.SocketOrChannelConnectionImpl.write(SocketOrChannelConnectionImpl.java:724)

        at com.sun.corba.se.impl.protocol.CorbaClientDelegateImpl.invoke(CorbaClientDelegateImpl.java:129)
        at com.sun.corba.se.impl.protocol.CorbaClientDelegateImpl.is_a(CorbaClientDelegateImpl.java:213)
        at com.sun.corba.se.impl.protocol.CorbaClientDelegateImpl.is_a(CorbaClientDelegateImpl.java:221)
        at com.sun.corba.se.impl.protocol.CorbaClientDelegateImpl.is_a(CorbaClientDelegateImpl.java:221)
        .....
        at com.sun.corba.se.impl.protocol.CorbaClientDelegateImpl.is_a(CorbaClientDelegateImpl.java:221)
        

A review of the CORBA code indicates problems in the method: com.sun.corba.se.impl.protocol.CorbaClientDelegateImpl.is_a. When a RemarshalException is caught, the is_a method is called again (to try again): hence continuous RemarshalExceptions will eventually cause the stack to overflow. Some way of limiting the number of recursive calls to this method, or throwing a different exception is needed.





REPRODUCIBILITY :
This bug can be reproduced often.
