Jawin failing after large number of object creations/uses

Hi

I've been testing Jawin with the view to using it in some applications
that run in app-servers.
The key point for me is that the applications will run for a very long
time, without being restarted.

I've run a few tests with various common COM components where objects
are repeatedly created, used and released.
All of the tests I've run eventually fail after a large number of
executions (depending on the particular COM object this can be 200,000
-> 50,000,000).

In all cases when the programme fails, the JVM locks.
Dumping the threads for the process reveals that the JVM is stuck in a
native method trying to print an exception stack trace, although any
attempts to print anything at this point fail (even String constants).
Running in a debugger reveals that a ComError is the error being thrown
- after which the running Thread gets deadlocked in
ClassLoader.findBootstrapClass( "java.util.Arrays" ) <native>.
My guess is that this is some kind of native resource exhaustion for the
process, which is why the JVM native methods are blocking.
The memory and virtual memory for the JVM process is pretty much static
throughout the run, and the Threads, Handles, GDI Object and User Object
counts are also static.
The Access Violation address (0x6D64A9DE) is inside the jvm.dll range
(0x6D640000)  (i.e. not in jawin.dll).

Has anyone seen this behaviour before, or have any ideas as to the cause?

Some other (fairly unsubstantiated) observations:
 - failure seems to happen earlier when an STA thread is used (object is
Both threaded).
 - failure seems to happen later when the thread is
CoInitialize/CoUnitialized for each object creation, and later still if
a single object is allocated and used repeatedly.

ComError:

at 0x830bec (description: The thread attempted to read from or write to
a virtual address for which it does not have the appropriate access)"

Test method:
--------------
    public static void main(String[] args) throws Exception {
        Ole32.CoInitialize(COINIT.MULTITHREADED);
        try {

            int i = 0;
            while (true) {
                DispatchPtr xr = new DispatchPtr("Msxml2.DOMDocument.5.0");

                Boolean load = (Boolean)xr.invoke( "loadXML",
"<foo>stuff</foo>" );

//                System.out.println( load );
//                System.out.println( xr.get( "xml" ) );

                if (i % 100000 == 0) {
                    System.out.println(i);
                }
                i++;
                xr.close();
            }
        } catch (Error e) {
            e.printStackTrace();
        }
        Ole32.CoUninitialize();
    }
