Java Compiler Compliance Level not working [message #1809392]

Hello everyone,,
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???

Please see that the compiler compliance only determines which language features can be used, while the problem you are describing is a matter of the runtime libraries.
Please make sure that the project is configured to compile against the correct version of JRE.
