Does the Java runtime allow loading and stashing the address of the routine he first time you need it and serializing access to it?

I have a Java JNI routine written in C and used as a wrapper to a venerable assembler program. The assembler program is neither re-entrant or reusable and to reflect this the JNI routine is linked RENT=NO and REUS=NO. However, the RENT=NO and REUS=NO does not appear to be being honoured, as the 1st call works and subsequent calls fail in the assembler routine. I imagine I could use LINK/LINKX to get around this, but I’d like to understand any JNI restrictions on z/OS.
