Went again thru the BSF4ooRexx code. Have not found anything, however a few
observations:
* When doing a RequestGlobalReference() on the argument array *and* its sole
entry, then the
program ran to the end without a problem.
* Adding additional output statements (that also caused more
call-to-Java-to-Rexx, calls to
SendMessage0() and CString()) caused the exception again. However much
further towards the end
of the test Rexx program.
This is the message scenario in this case:
RII=Rexx Interpreter Instance RII #1 RII # 2 BSF.CLS BSF4ooRexx.cc Java
(Host.rex)
(test_set_.rex) |------------------------->|------------>|----------->| |
|<--------------------------|<---- run test_set_.rex |
|-------------------------->|----------->| |
|<------------|<----------->|<---------->| |
|<------------------------->|<---------->| ... and so on ... |
|<------------|<------------|<-----------| |
|-------------------------->|----------->| |
|<--------------------------|<-----------| |
|------------>|------------>|----------->| ... and
so on ... | |--------------------------------------->| (end test_set_.rex)
|<---------------------------------------|<-----------| (end Host.rex)
* Everything is carried out in the same thread.
* "test_set.rex" causes a lot of calls to Java (via BSF.CLS) which may cause
a lot of calls back
into Rexx. (In this application a majority of the callbacks from Java are
related to appending
entries into Rexx array objects from Java.)
Today I would be able to help debug this in the next 30 minutes, then after a
meeting which ends in
about two hours, I would be able to work on this for three hours, and then
after a dinner meeting
(ending in 8 hours) I could work a couple of hours again on this.
So any hints, ideas what I could do highly appreciated! Again, please bear with
me, I still have to
get acquainted with debugging using a GUI! :)
