Error description
ABEND0C4 in Application server region.  Dump Title is:
DUMP TITLE=COMPON=WEBSPHERE Z/OS, COMPID=5655A9801,ISSUER=
BBORLEXT, ABEND in *PATHNAM/unicode2UTF
Looking at the Traceback: of the ABENDING TCB from the SVC Dump
(using the IPCS command: <IP VERBX LEDATA 'CEEDUMP, ASID(xxx),
TCB(yyyyy), DSA(zzzzz)'> at the top of the traceback you will
see:

.
The exception is occuring in method 'unicode2UTF', which is a
java method, but is caused because the WebSphere code does not
check for the 'printerr' call to be passing a 'null' string.
It is the responsibility of the caller of the jni call.

* PROBLEM DESCRIPTION: ABENDS0C4/ABEND0C4 occurs while trying  *
*                      to print a null object using println    *
*                      in the System.err outputstream.         *
*                      The WebSphere Application Server code   *
*                      is intercepting the println call and    *
*                      rather than passing the call to the     *
*                      JVM, which can handle a null object     *
*                      in println. When the WebSphere          *
*                      Application Server code passes the      *
*                      null object to the JNI the abend        *
*                      occurs.                                 *

****************************************************************
The method "println" in the PrintStreamErrWriter class needs to
check that it has not received a NULL java.lang.String as its
input parameter before calling StubServices.println.
The StubServices.println method makes a JNI call to C++ which
in turn calls the JNI function getStringUTFChars.  This
JNI function assumes that the string being passed is not NULL
and does not check the string before creating a UTF string out
of the string being passed.  So when a null string is passed
it causes an ABEND0C4 and the JVM is unable to recover.
Problem conclusion
The JVM handles a null object in println by returning a
string containing the characters "null" as output. To keep the
output from StubServices.println acting like the JVM, a check
has been put in the PrintStreamErrWriter class to see if the
string being passed is null and if it is then return a string
that contains the character string "null" to the output stream.
