For the JDK 116 release on the OpenVMS platform running on DIGITAL's
hardware, DIGITAL has changed, the following JDK 116 source file
in the shared part of the JDK.

A potential bug footprint occurs, i.e. an unhand followed by a memory operation that can provoke GC followed by a use of the unhanded pointer;

src/share/java/lang/io.c
* @(#)io.c 1.55 98/07/01^G

Added called to unhand directly before use of thisptr:
 i.e. dataptr = unhand(data)->body
