Issue using SCO java SerialDemo [CLOSED]

I recently installed the Java Communications API (v2.0Aa) on SCO and I'm having some issues running the SerialDemo application that comes with it.

I can open a connection and send text from SCO to a toy windows app I wrote - that works fine. However, when I try and close the connection, I get the following error:

libthread error: _thr_sigacthandler: fault 1 inside a critical section

What follows after that is a mass of debug text with various values (I don't know what any of it means). Can anyone suggest anything I could read up on to try and figure out what the error actually is? Is more information stored in log files anywhere?

If it helps at all, the offending line in the java program is when the SerialPort object is being closed.

Any suggestions are welcome. I didn't want to immediately just dump the whole thing here and hope someone else can glean something useful from it.

AIRPORT-MODEM(1)					      General Commands Manual						  AIRPORT-MODEM(1)

NAME

       airport-modem  - Modem monitoring and hangup utility for the original Apple AirPort Base Station ("Graphite"), the Lucent RG-1000 base sta-
       tion and the Apple Airport Extreme base station

SYNOPSIS

       airport-modem

DESCRIPTION

       airport-modem allows you to monitor the state of the internal modem of your base station and to start/stop the modem connection.

       On the AirPort Extreme base station, the modem utility can also display the approximate duration of the modem connection.

OPTIONS

       airport-modem accepts no command-line options. airport-modem is a wrapper script around the AirportBaseStationHangup.jar jar  file  located
       in /usr/share/java/airport-utils.

       You  can set the JAVACMD environment variable to use a specific JVM instead of the one chosen by the wrapper script. Set the DEBUG environ-
       ment variable to 1 to get the debug output from the wrapper script.

ENVIRONMENT VARIABLES

       DEBUG  Set this variable to 1 to get the debug output from the wrapper script.

       JAVACMD
	      The full path to the Java Virtual Machine to use.  By  default,  the  wrapper  uses  JAVACMD;  if  it  is  not  set,  it	looks  for
	      JAVA_BINDIR/java, then for JAVA_HOME/bin/java before looking for a java executable in the PATH. In the latter case, the JVM used can
	      be configured using the Debian alternatives system (see update-alternatives(8)).

       JAVA_HOME
	      The full path where your JDK/JRE is installed.

       JAVA_BINDIR
	      The full path to the directory where the java executable is located.

       JAVA_ARGS
	      Extra command-line arguments to be passed to the Java Virtual Machine.
