Is JNI (Java Native Interface) Known to Work in Both Directions on FreeBSD (to invoke the JVM from native software)?

[Rod]

Guys

Thanks for your help with this.
After re-building jdk16, I was able to run the simple c++ invocation program
to invoke a JVM via the JNI.
For some reason however, I still get the SIGSYS with R and rJava so I'll
contact the rJava developers next.

Regards

Rod.
