Summary
-------

Deprecate for removal the class `java.util.zip.ZipError`.

Problem
-------

`ZipError` was introduced via JDK-4615343 in JDK 6 and extends `java.lang.InternalError` to maintain compatibiliy with any existing client code catching `InternalError`. 

Its usage was removed from `ZipFile` in JDK 9 when the use of native code transitioned to Java via JDK-8142508. The only other use was in the original `ZipFS` demo which also was removed when ZipFS was integrated into JDK 9 as a supported Module. The JDK never documented in any API specification that `ZipError` was thrown. 

The ZipError class is easy to confuse with similarly named `ZipException` class in the same package. It is not suitable for general-purpose ZIP exceptions as it extends InternalError, yet there is no warning against its usage.

A corpus search on GitHub and Maven showed only a handful of uses.

Solution
--------

Mark the class `java.util.zip.ZipError` as deprecated, for removal.

Affected client code should be updated to catch or throw `ZipException`. Code base needing to catch `ZipError` on JDK 8 should catch the super class `InternalError` instead.

This specification change will be accompanied by a Release Note in the release it is approved for.
