Trace All vs. Trace Results

Mike Cowlishaw-3
The NullPointerException is being raised by the toString method of the
Perl5Util class, so it looks like the problem is there.

When TRACE RESULTS is turned on, NetRexx tracing calls the toString
method of an object being traced, to get the string to display.  That
method should always return a String -- but in this case it fails.

I don't think NetRexx is at fault either.  I've snatched up these tools to explore and have
found they will error out quite easily. I haven't had them long enough yet to explore
where the problems are but the failures are very repeatable even using sample code
provided.

Following up on my own post :-)

I've discovered that the Perl tool kit for Java (www.oroinc.com) does not work at all in
my OS/2 system (Warp 4.0, fp5, 32meg, Java 1.1.4 with refresh). All packages from that
site work fine under NetRexx on NT and Sun Solaris, and all packages apart from Perl
work fine in Os/2. I don't know why OS/2 fails with the Perl tools (cpu usage goes to max  
and programs never finish) but it is disappointing.
