Fixed in [rev. 1242108](http://svn.apache.org/viewvc?rev=1242108&view=rev)
The cause of this error is already in the beginning of the call, but only at
the end it is causing trouble.
The reason: while reproducing this issue the workDirectory is a single
filename. When the commandline is built it first calls
`workingDirectory.getParent()` and then it uses its `getAbsolutePath()`. In
this order the parent can't be calculated, so when calling the
`getAbsolutePath()` you'll get your NPE. If the workingDirectory was `rx/ry`
you would have had no problem.
> NPE when workingDirectory is null
