RFR: 8280409: JarFile::verifiableEntry can fail with NPE accessing ze.getName()

[Lance Andersen]

Hi all,

Please review the attached patch to address

- That JarFile::getInputStream did not check for a null ZipEntry passed as a parameter
- Have Zip/JarFile::getInputStream throw a ZipException in the event that an unexpected exception occurs

Mach5 tiers1-3 runs are clean as are the TCK java.util.zip and java.util.jar test runs

Best
Lance
