I have a project that I built for jdk 7, but I want to expand its compatibility for jdk 6 users as well. I have set the compiler compilance level to 1.6, but the project compiles normally, and fails running on a 1.6 jre due to the fact that the method revalidate was not added to java until java 7. (and the compiler didn't give ANY warnings about this at all!) How can I set the source level to 1.6 as well? I could do this in netbeans, any way on how to do this in eclipse?

Properties> Java Compiler > JDK Compliance, make sure to set to proper compiler version.

I had similar issue after setting my compliance level and ensuring I had proper run time. To resolve I had to run Project then Clean... and specify project name. This took care of the issue for me.

In addition to source compability also set "compiler compliance level" and "generated .class files compatibility" in your project settings.
