#5 GUI unit tests fail on Ubuntu 10.04

[Marin Lagace]

Unit tests for MagnitudeField fail when initializing the UISpec4J framework.

The tests fail on Ubuntu 10.04 (Lucid Lynx) with OpenJDK:
$ java -version
java version "1.6.0_20"
OpenJDK Runtime Environment (IcedTea6 1.9.10) (6b20-1.9.10-0ubuntu1~10.04.2)
OpenJDK 64-Bit Server VM (build 19.0-b09, mixed mode)

The test pass on Windows with Sun JDK:
# java -version
java version "1.6.0_30"
Java(TM) SE Runtime Environment (build 1.6.0_3--b12)
Java HotSpot(TM) Client VM (build 20.5-b03, mixed mode)

I have not tried with the Sun JDK under Linux.

The problem is related to OpenJDK. UISpec4J only works on the Sun/Oracle JVM.
See http://tech.groups.yahoo.com/group/uispec4j/message/829.

Perhaps FEST (http://code.google.com/p/fest/) could be used instead.
