Description

On Mac Snow Leopard with MATLAB releases prior to R2012a, groovy.ui.Console() gives class not found errors.
This seems to occur on UNIX systems generally - not on Windows. The originating exception is

java.lang.NullPointerException
at java.util.prefs.AbstractPreferences.node(Unknown Source)

Operating System: Mac OS X Version: 10.6.8 Build: 10K549
Java Version: Java 1.6.0_29-b11-402-10M3616 with Apple Inc. Java HotSpot(TM) 64-Bit Server VM mixed mode

This is used by all MATLAB installations on the Mac (it does not ship with its own for Mac) and tests were done for several releases on the same machine.

MathWorks support tell me this is an issue with other software too on UNIX systems. I have tried only MATLAB and Windows+MacOS so far.

NB Line 66 vs 77 difference in groovy.ui.Console in the OP. I think I have tracked this to the use of a different Groovy release - it's line 77 for 1.8.6 but 66 for 1.6.4 which was used for some checks. For 1.8.6 that is:

static private prefs = Preferences.userNodeForPackage(Console)
