Hello FreeBSD java experts:


I created a little c++ test program to launch the java vm (JDK1.6.0 on Freebsd 7.0) from native code with jni:


...
...
     //
     // Pertinent line of code in test prog
     // 
     JNI_CreateJavaVM(&jvm,(void **)&env, &vm_args);
...
...


When the test program is executed with truss, the following partial result indicates that  a call to non-existent ksem_init call is causing SIGSYS.

...
...

SIGNAL 12 (SIGSYS)


Subsequent culling of mailing list indicates that 7.0-RELEASE GENERIC kernel does not enable P1003_1B_SEMAPHORES, and so the "Function not implemented" messages is reasonable.  Before I go to rebuild the kernel with with additional semaphore option, can anybody tell me if there are issues/caveats with doing this?

 - Thanks
