No clue with an exception (NullPointerException) due to a properties retrieval thrown by the IBM MQ

I'm having this exception thrown by the IBM MQ which I'm struggling with, I have no clue why this is happening. Here it comes:

java.lang.NullPointerException
    at com.ibm.mq.jmqi.JmqiEnvironment.getVersionProperty(JmqiEnvironment.java:2204)

    . . .

I'm having two scenarios, (1) A stand-alone one-threaded app which runs okay (jre6), but I'm having troubles when I use this (2) as part of a library used by a multi-core environment (using the 1.4.2 JVM).

Reproduced Code

MQEnvironment.hostname = Host;
MQEnvironment.channel = Channel;
MQEnvironment.port = Port;
MQEnvironment.userID = QMUser;
MQEnvironment.password = QMPass;

MQQueueManager qmanager = new MQQueueManager(QueueManager);
MQMessage mqmessage = new MQMessage();
MQPutMessageOptions mqputmessageoptions = new MQPutMessageOptions();
MQQueue mqqueue = qmanager.accessQueue(QueueReq, 8208, null, null, null);

mqmessage.format = MQC.MQFMT_STRING;
mqmessage.persistence = 1;
mqmessage.replyToQueueName = QueueResp;
mqmessage.expiry = -1;
mqmessage.priority = -1;
mqmessage.writeString(MWAS);
mqmessage.messageId = "".getBytes();
mqmessage.correlationId = "".getBytes();

mqqueue.put(mqmessage, mqputmessageoptions);

mqqueue.close();

The execution doesn't even get to the instantiation of the MQQueueManager, the exception is thrown when assigning the MQEnvironment's static attributes.

Extra Info

The running OS is Windows 2003 Server R2 Enterprise SP2 (x64). The JVM is the Sun's 1.4.2_10 (x86). The WMQ version is 7.0.1.5. Some system properties are: java.runtime.version=1.4.2_10-b03, java.vm.vendor=Sun Microsystems Inc., os.arch=x86.

What could this be?

Thank you in advance.

What do you mean by the "the 1.1.0 MS JVM"? I can see from the stack trace that you're using the v7 MQ client - the JVM requirements are listed here

http://www-01.ibm.com/support/docview.wss?rs=171&uid=swg27011920

Assuming you're 32-bit, the supported options are

Java 2 Platform, Standard Edition (J2SE) V1.4.2 from Sun Microsystems, Inc. 
Java 2 Platform, Standard Edition V5.0 (SR1 or above) from Sun Microsystems, Inc. 
Java 2 Platform, Standard Edition V6.0 from Sun Microsystems, Inc. 
IBM 32-bit SDK for Windows, Java 2 Technology Edition, V1.4.2 
IBM 32-bit SDK for Windows, Java 2 Technology Edition, V5.0 (SR1 or above) 
IBM 32-bit SDK for Windows, Java Technology Edition, V6.0 

So I suspect that the code is throwing a NullPointerException because an unsupported JVM is unexpectedly returning null when the WMQ Java client is querying a system property.

Most likely this happens, when you try to access a data structure [which is not synchronized inside] with multiple threads without a lock.

One of the object you are accessing in the stack trace is not multi threadble and you need a lock.

One example being HashMap [as against hashtable] - try to use it with multiple threads without a lock outside.
