Running various test programs repeatedly the crashes can be observed, if:
* at least two (or more) Rexx interpreter instances are used to execute code
concurrently (not
necessarily on different threads)
* in the JavaFX case: the second Rexx interpreter instance will be used to
execute Rexx code on
the Java created "JavaFX Application Thread" ("GUI thread"), and if a crash
occurs, it is in
this thread trying to run Rexx code on that second Rexx interpreter
o upon the call from Java( on the GUI thread) into BSF4ooRexx,
relinquishing control of the
thread (and waiting 1/100sec on Windows) before doing a Rexx
AttachThread() followed by a
SendMessage() seems to run almost stable (have never experienced a
crash in this situation,
but observed in very rare cases, maybe once every 100 tests, a
hang/deadlock);
+ it is - maybe a wild - guess that relinquishing the thread allows
some parallel running
Rexx thread (garbage collector?) to conclude, such that the
AttachThread() on the GUI
thread on the second Rexx interpreter instance is executed without
problems
# this is from observing the stack traces which always seem to
lead to the need of
getting Rexx memory
* there are a few BSF4ooRexx test-units purposefully crafted to stress-test
multithreading usage
of BSF4ooRexx (interacting with Java from different Rexx threads, using
Java to create many Rexx
interpreter instances on different Java threads and then running Rexx code
concurrently among
the Rexx interpreter instances, etc.)
o the crashes occur 99% in one test unit
("80_test_MultiThreading_via_Java_threads.testGroup")
in the context of NewRoutine() (gets created from the supplied code)
which then is run using
CallRoutine(); also the crash, if it happens, happens rather late into
the test (which takes
almost a minute); here a brief description:
+ the test group creates 23 Rexx interpreter instances each on a
different Java thread
(employing a Java class named "TestNestedEngines_80.java"),
+ the Rexx test program
("80_test_Multithreading_via_Java_threads.rex") gets called on
each Rexx interpreter instance on a separate Java thread and will
create 29 instances of
a Rexx class and send it a message ("work"), which will do a
"reply" before continuing
its work
+ including the overhead, this test causes 712 threads to be created
and used
o currently, the crashing test unit has become much more stable by doing
six (!) thread
relinquishings (each waiting at least 1/100s) before doing an
AttachThread() followed by
native calls into Rexx
+ occassionally, though very rarely (maybe once every 100 runs) a
hang occurs when running
this test unit (looking at Sysinternal's process explorer there are
about five threads
active and a lot in endthreadex)
# for the hanging Rexx thread (appr. 25% of CPU, after 20 minutes
looking at
3,000,000,000 cycles and increasing) please find a snapshot of
that stack below
o below please find an excerpt of the current set of hs_error*log files
which show, in which
Rexx function the crash occurred (tried to keep the excerpt as short as
possible)
Speculation: the garbage collector thread may not be "multiple Rexx interpreter
instance" safe or
AttachThread()/DetachThread() on a non-primodal ("a different") Rexx
interpreter instance may not be
aware that the garbage collector is concurrently running.
----
Hope these observations help, they have cost me an awful lot of time and
efforts (including weekends
and nerves :) )!
