Trying to run Windup v.2.3.0 Final (Windows 8.1 Enterprise) against some legacy code I inherited from:

D:\java-practise\windup-distribution-2.3.0.Final> bin\windup --input D:\java-practise\test-workspacebin\windup --overwrite --output D:\java-practise\test-workspace\OUTPUT_REPORT_DIRECTORY

get:

Exception in thread "Thread-1" java.lang.AssertionError: Should not get here

        at sun.nio.fs.WindowsFileAttributes.volSerialNumber(WindowsFileAttributes.java:387)

        at sun.nio.fs.WindowsWatchService$Poller.implRegister(WindowsWatchService.java:362)

        at sun.nio.fs.AbstractPoller.processRequests(AbstractPoller.java:260)

        at sun.nio.fs.WindowsWatchService$Poller.run(WindowsWatchService.java:533)

        at java.lang.Thread.run(Thread.java:745)

Also --help gives the same:

D:\java-practise\windup-distribution-2.3.0.Final> bin\windup --help

        at java.lang.Thread.run(Thread.java:745)

Any pointers?

***** UPDATE *****

Download the windup-distribution-2.3.0.Final to my Mac OS X Yosemite and windup runs okay from terminal.

So it must be a Windows 8 issue?
