I'm getting LinkageError: bad major version at offset=6, while deploying app on S60 Emulator

I actually developing J2ME project using S60 SDK, my project gives me the error,

Uncaught exception!
com.ibm.oti.error.LinkageError: (com/yoke/symbian/YokeApp) bad major version at offset=6

Because I'm changing compliance level of project from 1.3 to 1.6 (I've installed) from ProjectProperties -> Javacompiler.

Basically when I'm creating new project from git repository it default comes with compliance level 1.3 so, I changed it.

Because in two classes I'm using String... & @SuppressWarnings("rawtypes")

This error continue if I change back compliance level to 1.3.

I don't understand why it's happening. I exactly can't sort out. But the only way I found is to create new project.

Please help.

Stop using annotations and go back to Compliance level 1.3.

java-me development does not support Compliance level 1.5.

java-me code does not support annotations.
