Hi there,
I am getting an error using gcj 1.5.x I was not getting in older
release, and I do not understand what I am doing wrong.

I really need a test case for this. Something I can build.

Everything is open source. Ref build failure on automated debian build
system (hppa machine):
https://buildd.debian.org/~luk/status/package.php?p=gdcm
The problem is that this is quite complex to build on a non-debian
system. Does redhat system comes with a system installed 'vtk.jar'
file ?
To reproduce you need to get VTK package, turn java wrapping on. Then
build GDCM against that VTK version. If you need more info, please
contact me directly.
Thanks,

Sure, but I don't see what would stop your from extracting the relevant
files into a test case that anyone can try.

Oh sorry :)
Does this help:

Thanks to Andrew, I was able to track down the issue to a problem with
the javac wrapper as distribute in the debian linux distribution.
Which basically provide a javac Sun-like cmd line, and forward args to
gcj. Namely:
...
} elsif ($arg eq '-classpath' or $arg eq '--classpath' or $arg eq '--cp') {
$appendNextArg = '--classpath=';
...
Thus -cp was never taken into account.
Sorry for the noise,
