[9] request for review: 8049171: Additional tests for jarsigner's warnings

[Wang Weijun]

Thanks for adding so many tests. Some suggestions:

- JarUtils.java

You can use the new InputStream.transferTo() method.

I am not sure if I understand updateJar correctly. It looks like srcJarFile is opened multiple times so its entries are duplicated a lot in the destination. Or is there a secret break?

- Utils.java

The mixed using of File and Files is strange, but you are free to keep it.

- TimestampCheck.java

You can make Handler Autocloseable to use try-with-resources in tests.

- Various tests

I am not a fan of calling Utils.cleanup() in final block. Unless you have created huge garbages, those files are precious when the test fails (given you provide -retain in jtreg, which I always do).

Thanks
Max
