To start, I'm an x10 newB ;-) I installed X10 on our cluster (CentOS 6.2) and
decided to run through the platform tests on SourceForge to get a handle on X10
and ensure everything was running properly. There are a variety of runtime
failures I'm working through at this point, but one in particular has me
curious.
Here is what I have running:
x10-2.2.2.2-src.tar.bz2 from SourceForge, unzipped
Linux/x86_64 (RHEL6) Download for the Runtime (x10-2.2.2.2_linux_rh6_x86_64.tgz)
I replaced the source x10.dist with a soft link to the downloaded binaries
lrwxrwxrwx 1 paul.monday dev 23 May 23 10:06 x10.dist ->
/mnt/shared/x10-2.2.2.2
[paul.monday@pg73-v0 examples]$ x10c -version
x10c version 2.2.2
Polyglot compiler toolkit version 3.2.0 (2010-06-03 19:23:58)
I'm curious about two things, in the
Constructs/IndexedMemoryChunk/Congruent.x10 test, C++ passes, Java fails. Is
this a JDK compatibility problem, or possibly a 2.2.2.2 compilation issue when
it was built? Next, I'm sort of curious how often these incompatibilities pop
up. I have other failures I'm working through in the test suite, this one was
the first that really caught my attention.
The logs and code follow for C++ followed by Java
Here is the C++ log:

imc.getCongruentSibling(p.next()).remoteAdd(i, oracle);
Here is the Java emitted code that it Fails on:
