Comment 5 for bug 1813494

I added the feature this way:

App app = new App("C:\\Path\\to\\runnable.exe");
app.setWorkDir();
app.open();

which sets the working directory to the absolute path of the directory the runnable is located.

If you want to specify a different or separate working dir:
App app = new App("C:\\Path\\to\\runnable.exe");
app.setWorkDir("C:\\Path\\to\\someOtherDir");
app.open();

I would appreciate your tests (could not yet test it on Windows ;-)

fixed as 2019-02-03 build #190
