Steps To Reproduce:
1. Make JAVA_HOME a java6 jdk, select that in eclipse as jre

This is not controlled by compliance level, but simply by the choice of the library you use on the classpath. If you develop for Java 5, you should point at a Java 5 library on your classpath.

Sounds like bug 231260 though I'm surprised it hasn't been closed as yet.
