> Please review this PR that enables ClassWriter to write annotations to the 
> class file being dumped.
> 
> The fields annotations are stored in `Annotations::_fields_annotations` which 
> is of type `Array<Array<u1>*>`. There is no class in SA that can represent 
> it. I have added ArrayOfU1Array to correspond to the type `Array<Array<u1>*>` 
> and it works. I believe there are better approaches but that would require a 
> bit more refactoring of the classes representing Array types. I will leave 
> that for future work for now.
> 
> Testing: `test/hotspot/jtreg/serviceability/sa` and `test/jdk/sun/tools/jhsdb`
> Tested it manually by dumping j.l.String class and comparing the annotations 
> with the original class using javap.
> The test case mentioned in 
> [JDK-8311101](https://bugs.openjdk.org/browse/JDK-8311101) would provide 
> better coverage.
