Explanation
A useful reference for information about the Java™ Attach API can be found at http://docs.oracle.com/javase/8/docs/technotes/guides/attach/index.html. The following extract is taken from the Oracle documentation:
The Attach API is an extension that provides a mechanism to attach to a Java virtual machine. A tool written in the Java Language, uses this API to attach to a target virtual machine and load its tool agent into that virtual machine.
A usage example is to late attach the IBM® Health Center agent to a virtual machine (VM) that is already running.
The Eclipse OpenJ9™ implementation of the Attach API is equivalent to the Oracle implementation. However, the OpenJ9 implementation cannot be used to attach to, or accept attach requests from, other VM implementations.
