RFCOMM write crashing on OSX 10.6.2

[GoogleCodeExporter]

What steps will reproduce the problem?
1. compile latest SVN (3027) on Mac OSX 10.6.2 after changing target to x86_64 
(compilation 
using mvn, passing all tests: Tests run: 52, Failures: 0, Errors: 0, Skipped: 0)
2. running bluecove-tester (java -cp 
/PATH_TO_LIB/bluecove-2.1.1-SNAPSHOT.jar:bluecove-
tester.jar net.sf.bluecove.se.Main)
3. opening an RFCONN connection using: more -> client connection -> connect 
(all works fine)
4. trying to send anything (in example: "test") as String.getBytes()+CR or as 
String.getBytes()
5. application crashes

The same happens if writing a Java application with the following code:

StreamConnection conn = (StreamConnection)Connector.open(bd.getServiceUrl());
OutputStream os = conn.openOutputStream();
String testStr = "test_string";
os.write(testStr.getBytes());

Please note that reading from the channel works fine.

What is the expected output? What do you see instead?
The client should keep on working, instead it crashes with the attached report

• Changed state: Accepted

[GoogleCodeExporter]

If I could be of any help, for what I'm doing I just completely commented out 
the code in:
OSXStackRFCOMM.mm
RFCOMMChannelController::rfcommChannelWriteComplete(void* refcom, IOReturn 
error) (line 175 to 182)

In this way the data gets transmitted, but of course the sending doesn't get 
"acknowledged" and therefore the 
sending thread doesn't know whether data has been sent or not. It's just a 
"dirty" fix to have bluecove 
"working" waiting for an official fix from your side.

Thank you very much for noticing this issue!

It looks like we faced the same problem. I'll attach crash log in case it helps 
research the issue.

Is there any information on what causes the problem? Can we somehow avoid it?
