RFR(XS): 8013364 SA-JDI exceptions caused by lack of permissions on OSX should be more verbose about issue cause

[Staffan Larsen]

Hi,

This is an improvement to the error message the user receives when SA attach fails on OS X. The current message is:


attach: task_for_pid(13581) failed (5)
Error attaching to process: sun.jvm.hotspot.debugger.DebuggerException: Can't attach to the process


This is changed to:


ERROR: attach: task_for_pid(89) failed: '(os/kern) failure' (5)
Error attaching to process: sun.jvm.hotspot.debugger.DebuggerException: Can't attach to the process. Could be caused by an incorrect pid or lack of privileges.
