[DRMAA-WG] normal exit status causes drmaa_wifaborted

[Tim Harsch]

Daniel,
    By what method does the Java binding, bind to the C binding ( e.g. the 
perl binding uses SWIG... )

I'm diving into the Perl binding now, but its been about 4 years since I 
wrote it.... so it's gonna take me some time I think.

PS It's really odd, the problem showed up in code I've put in regular use 
for a long time, I know bugs just don't introduce themselves, but this part 
of the binding worked fine, I haven't upraded SGE or Perl or recompiled 
Schedule::DRMAAc but the problem just appeared.  I'm thinking the sysadmins 
ran up2date on my RH4 box and a dependency library to the C binding changed. 
But, if your Java binding is actively using it, then it would rule that 
out...
