What steps will reproduce the problem?
1. Use Java 1.5 
2. Try to compile with GWT compiler
3. Fails to compile. If changed to a Java 1.6 compiler this issue does not 
occur.

What is the expected output? What do you see instead?
Compilation succeeds.

What version of the product are you using? On what operating system?
gwt-g2d-v007.jar

Is there a reason why you need to use Java 1.5 instead of 1.6?
