Remy,
This is a known problem on all versions of Java. Here is the quote from
the Java Series Book, "The Java Native Interface" by Sheng Liang:
"Unfortunately, you cannot unload the Java virtual machine implementation
in JDK release 1.1 or Java 2 SDK release 1.2. DestroyJavaVM always
returns an error code in these releases."
I don't whether this means that it will be fixed in 1.3? In any event, in
the case of a C program, my experience is that the JVM is unloaded when
your program terminates. In the case of a C DLL, we basically make sure
that we load the JVM only once since we cannot destroy it. When the C
DLL leaves memory, the JVM may be destroyed. So far, this approach has
worked OK for us.
