After further excessive (literally additional days of) debugging I can state that upon Rexx
interpreter instance (RII) terminations using the native Terminate() API, ooRexx does not
release/run the uninit methods of at least the monitored objects (ooRexx BSF objects) of the .local
monitors!
=====
Here the relevant parts after creating, using and Terminate() 1,000 RIIs:

Here the relevant parts after creating, using and Terminate() 1,000 RIIs, this time running the
following Rexx program right before termination of a RII from the Java side:
... cut ...
/String rexxCode = // reset .input, .output, .error,
.traceOutput, .debugInput to free BSF
objects if any " lDir = .local -- get .local ;\n" + " lDir['INPUT' ]=
.monitor~new(ldir['STDIN'
]) ;\n" + " lDir['OUTPUT' ]= .monitor~new(ldir['STDOUT']) ;\n" + "
lDir['ERROR' ]=
.monitor~new(ldir['STDERR']) ;\n" + " lDir['TRACEOUTPUT']= .monitor~new(ldir['ERROR'
]) ;\n" + "
lDir['DEBUGINPUT' ]= .monitor~new(ldir['INPUT' ]) ;\n" ; /
Object obj=null;
try {
obj=rexxInterface.jniRexxRunProgram(
rii_ID, // RexxInstance instance ID
2, // invocationType, // determines whether
"CallProgram", "LoadPackage" or "LoadPackageFromData" is to be used
"RexxEngine_terminate_cleanup_local_monitors" , // fileName
/rexxCode /, // Rexx code to execute
null // arguments
);
}
... cut ...
res=rexxInterface.jniRexxTerminateInterpreterInstance(rii_ID); // wait for
termination of all Rexx threads of this interpreter instance
... cut ...
Doing this for every RII will cause the UNINIT method of the BSF objects to be run, correctly
removing the pinned (peer) Java objects:
