Java Compiler Compliance Level not working [message #1295969]

I'm working on a project that requires Java 1.5 compliance. Yes I know that's old, but that's what is being used. There are no project specific settings, so the main setting should be used.

I set the compiler compliance level to 1.5, yet I was able to use the String:isEmpty() function in code without the Eclipse compiler complaining at all. This resulted in an application that is not runnable using Java 1.5 as the String::isEmpty() function was added in Java 6.

Shouldn't the Compiler Compliance Level setting notify users if a function is being used that isn't compatible with the version set?

No - the compilance level only influences the byte-code format. If 1.5
is your target then you better have 1.5 installed and configured in your
IDE as a JRE.
