As part of JEP 260, all non-Critical APIs in sun.misc are being examined. sun.misc.VMSupport is a utility class supporting two functions: 1) the initialization of management Agent properties, and 2) the retrieval of the VM temporary directory used by the attach and perf data files.
The initialization of Agent properties is used statically by the java.managment module, or can be provoked by a serviceability tool on a VM that has had an agent loaded in it. The location of VM temporary files is a low-level interface between the libraries and VM. For these reasons, VMSupport should remain in the base module, but be moved to an internal package. http://cr.openjdk.java.net/~chegar/8153181/00/ https://bugs.openjdk.java.net/browse/JDK-8153181 -Chris.
