EXCEPTION_ACCESS_VIOLATION (0xc0000005) in pfcasyncmt.dll

[sandbornm]

Hello, I am getting an Exception Access Violation when running the creoson server to automate the assembly of designs in Creo Parametric 5.6.0.

Crash output:

To Reproduce

The command line args (from attached log file) -Dsli.jlink.timeout=200 -Dsli.socket.port=9056 com.simplifiedlogic.nitro.jshell.MainServer

I have tried changing the jlink timeout to something like 9999, but the same error occurs. It looks like the crash may be indirectly related to the pfcasyncmt.dll. I have also posted about this issue to corretto-11 issues as well as the PTC community forum but have not found a solution. I apologize if this is the wrong place or has been addressed before.

Unfortunately, I do not have many details with respect to consistently reproducing the issue, but it seems to be originating in the function com.ptc.pfc.Implementation.pfcSession$Session.GetModelFromFileName(Ljava/lang/String;)Lcom/ptc/pfc/pfcModel/Model; but I am not sure if this code is open source. Thank you!

The creoson server is started from the command line from a .bat script with the following command:

"%JAVA_HOME%\bin\java" -classpath "%cp%" -Dsli.jlink.timeout=9999 -Dsli.socket.port=%JSON_PORT% com.simplifiedlogic.nitro.jshell.MainServer

and the environment variables are (see attached logs for more context):
