Description
If you use 'java -agent:unknown' you will get the error message:

    Error occurred during initialization of VM
    Could not find agent library on the library path or in the local directory: unknown

The term 'local directory' is very confusing, the current directory is not searched. I think this 'local directory' is the JDK bin or library directory inside the JDK installation.

I think a shorter message would be better: Could not find agent library: unknown

EVALUATION Suggested fix sounds appropriate. This is an easy fix and cuts down on confusion.

SUGGESTED FIX In file hotspot/src/share/vm/runtime/thread.cpp agent libraries are searched for in the JDK first, then via the platform specific search, if both fails, the user sees: vm_exit_during_initialization("Could not find agent library on the library path or in the local directory", name); I suggest a change like: vm_exit_during_initialization("Could not find agent library", name);
