RELEASE NOTES: JDK 8u144

java.util.zip.ZipFile.getEntry() now always returns the ZipEntry instance with a '/' ended entry name for directory entry

The java.util.zip.ZipEntry API doc specifies "A directory entry is defined to be one whose name ends with a '/'". However, in previous JDK releases java.util.zip.ZipFile.getEntry(String entryName) may return a ZipEntry instance with an entry name that does not end with '/' for an existing zip directory entry when:

• the passed in argument entryName does not end with a '/', and
• there is a matching zip directory entry with name entryName + '/' in the zip file.

With this release, the name of the ZipEntry instance returned from java.util.zip.ZipFile.getEntry() always ends with '/' for any zip directory entry.

To revert to the previous behavior, set the system property jdk.util.zip.ensureTrailingSlash to "false".

This change was made in order to fix a regression introduced in JDK 8u141 when verifying signed JARs and has caused some WebStart applications to fail to load. See JDK-8184993 for more information.
