java.lang.annotation.ElementType previously has element ANNOTATION , new PIT build doesn't have this element, This change prompted for compiler crash. This should say proper error message rather to crash.

The compiler crashes when u apply isAnnotation Method on old version class file.
following is the code and bug request trace.

public class AttributeAttrTest {

    private Class target;

    public AttributeAttrTest(Class cls) {
        this.target = cls;
    }
    
    public boolean hasAnnotationsOnAttribute() throws Exception {
        if ( target.isAnnotation() ) {
            ATTRAttribute[] attrs ;
            ATTRAttributes attr = target.getAnnotation(attrs.Class);
            if (attr.getValue().equals(target.getName() ) ) {
                return true;
            } else {
                return false;
            }
            
        } else {
            return false;
        }
    }
    
}

javac -source 1.5 AttributeAttrTest.java
