java.util.zip.ZipError seems unused

[Lance Andersen]

Hi Eirik,

The removal of ZipError from ZipFile/ZipFileSystem/ZipFileSystemProvider  occurred via 8145260 and 8037394 for JDK 9

The test should also be re-written at this point

Jai or I can make a pass to see if there are any external usages via a corpus search but I tend to doubt it

Hi!

The java.util.zip.ZipError class seems unused in OpenJDK. I assume this is legacy from the native ZIP implementation in Java 8.

This exception class extends InternalError and seems to have been added in Java 6 to help compatibility with existing code catching InternalError (JDK-4615343)

This change also introduced the TestZipError test, which verified that ZipError was thrown while enumerating a ZIP file which was changed after being opened. The reimplementation of the ZIP implementation to Java (JDK-8145260) updated this test to expect a ZipException instead of the ZipError.

Given that this class has now fallen out of use in OpenJDK, should we:

1: Deprecate it
2: Deprecate it for removal
3: Do nothing, keeping it around has a low cost
4: Something else

It would also be useful if someone with access to a large code corpus could search for usages of this class so we could assess compatibility concerns of removing it.

Thanks,
Eirik.
