java exception

[gametimebrizzle]

I am getting the error below when attempting to run sdrtrunk, this happened randomly today - as I have been using this awesome program for a little while now...I'm not sure how to debug this.

How to reproduce:
using cmd/PS:
run_sdrtrunk_windows.bat

What I've tried:

• Reboot
• Remove / reinstall sdrtrunk + reboot
• Remove / reinstall JDK + reboot
• Remove / re{install|compile} JMBE + reboot

What I haven't tried:

• Reinstall ant
• altering PATH (I have checked the path, but see no reason to change anything)

Here is the exception thrown (followed by the full console output)

I do have an audio mixer at the ready...

ISSUE RESOLVED: Reason - my bluetooth speaker lost its paired state - after I removed the speaker from bluetooth devices and reestablished a connection everything works just fine.
