#31 RBUTILS-030: Tests fail with SUN JDK 6

Summary: Tests fail when run with SUN JDK 6.
Affected versions: 0.10, 0.11-SNAPSHOT-02

With JDK 6, 2 tests on RbChecker fail when they check all test inputs properties files.
They detect one error (key lang does not exist in the ResourceBundle) we do not get with other Java version (for this case, the error should have been detected by previous Java version).
There is also another difference: Java 6 detects missing locale RB whereas Java 5 detects no RB!!!!

WARN!: this may also mean that a bug exists in RbUtils (the key really does not exist in the target RB). So write tests to better check these cases.

Tests failed with SUN jdk1.6.0_02 on win32.
I'll try with other 1.6 updates.
