ODM and JNI

I am trying to access the system configuration database via the ODM C
functions called from JNI. My standalone program works fine, but when
I try the same code under JNI, it instantly crashes at the fist ODM
function call. It seems to be dieing on the call, not in the function
which leads me to believe that maybe -lodm isn't compiled
appropriately to be be called from JNI? The stack traces look like
this:

CpuInfoAIX.CpuInfoInitializeCacheFunction(), line 75 in "CpuInfoAIX.c"
Where that line is: path=odm_set_path("/etc/objrepos");
the code is properly encased in a pthread mutex, and I have lots of
other JNI code that is work. I'm using the _r variants of the xlc
compilers, and I have these env vars set:
AIXTHREAD_SCOPE=S
AIXTHREAD_MUTEX_DEBUG=OFF
AIXTHREAD_RWLOCK_DEBUG=OFF
AIXTHREAD_COND_DEBUG=OFF
export AIXTHREAD_SCOPE AIXTHREAD_MUTEX_DEBUG AIXTHREAD_RWLOCK_DEBUG
AIXTHREAD_CO
ND_DEBUG
Any ideas?
