alice-teacher Alice 3 and Netbeans "root directory not set" error

[Daniel Abeshouse]

 I found a work around.

At runtime the ApplicationRoot is setup and reads the property "
org.alice.ide.rootDirectory".
In there it looks for the platform directory that holds the OS specific
libraries like jogl and ffmpeg.

You can set this property in code before ApplicationRoot is used by calling:

  System.setProperty("org.alice.ide.rootDirectory", "./");

This could be the first line in main().
Make sure that second directory holds the platform folder with the required
libraries.
It is not quite a single file, but it can be run.

My verification of this is on my machine at the office. Unfortunately, my
VPN just updated, meaning it broke itself, so I may send further details
and corrections tomorrow.
