I cannot remember having seen such warnings in Maven builds that use javac. But 
when I turned the "Field declaration hides another field or variable" to 
"warning" in Eclipse, the  SupressWarnings ("hiding")  warnings were gone.

This post on stack overflow has a good overview. The "hiding" option seems to 
be coming from Eclipse's compiler, not from javac:

This appears to be the list supported by Oracle Java 1.8.0: 

* all
* auxiliaryclass
* cas
* classfile
* deprecation
* dep-ann
* divzero
* empty
* fallthrough
* finally
* options
* overloads
* overrides
* path
* processing
* rawtypes
* serial
* static
* try
* unchecked
* varargs

> JCasGen generate references to FsGenerator which was changed in 2.8.0 to have 
> generic type information.  So the resulting generated code causes warnings 
> about raw types being used.  Workaround - add a 
> @SuppressWarnings("rawtypes"), but a better thing would be to add the proper 
> generic arguments.
