RFR: JDK-8213103: RoundEnvironment.getElementsAnnotatedWith(Class) crashes with -source 8

[Jan Lahoda]

Hi,

When RoundEnvironment.getElementsAnnotatedWith(Class) converts the Class 
to TypeElement, it uses:
eltUtils.getTypeElement(eltUtils.getModuleElement(<class-module-name>), 
<class-name>)

But this fails with -source 8, as there are no module (so 
getModuleElement returns null, and getTypeElement checks the module 
parameter is non-null). The proposed fix is to avoid this code.

Any feedback is welcome,
