of that might prevent things from shutting down.
Just double-checked, Terminate() is issued on the same thread as
RexxCreateInterpreter().

Currently, I have been trying to debug the following problem: unloader
function does not run.
Scenario #1: there is the BSF4Rexx.dll which contains a loader and an
unloader function. If rexx.exe starts a Rexx program that then loads the
BSF4Rexx.dll, the loader runs and when the Rexx program ends, the unloader
runs.
Scenario #2: there is the BSF4Rexx.dll which contains a loader and an
unloader function. Java loads the BSF4Rexx.dll, not rexx.exe. Then Java
creates a Rexx interpreter instance, which starts a Rexx program that then
loads the BSF4Rexx.dll, the loader runs, *but* when the Rexx program ends,
the unloader does not run! Looking at the different code paths to scenario
#1, then the following can be observed:
a Rexx instnace is created using the following option (the package
definition defines the loader and unloader function), the loader function
executes:
RexxLibraryPackage pkg;
pkg.registeredName = BSF4Rexx;
pkg.table= bsf_package_entry;
options[0].optionName= REGISTER_LIBRARY;
options[0].option= (void *) pkg; // bsf_external_functions; //
options[1].optionName=NULL;
No AttachThread() nor DetachTrhead() are invoked.
a Rexx script is sent from Java via JNI and the above Rexx interpreter
instance is used to execute it using NewRoutine() and then
CallRoutine(); here an AttachThread() and a matching DetachThread() is
carried out.
Before the Java program ends, it will use JNI to Terminate() the Rexx
interpreter instance that got created and employed above. No AttachThread()
nor DetachTrhead() are invoked.
Going over the code-path of scenario #2 to the best of my knowledge, no Rexx
thread exists that would be executing, hence I would expect that the
unloader function would run.
Any ideas or hints what might be the cause in scenario #2 that the unloader
function does not run?
