The following are some of the notable bug fixes included in this release:

Area: tools/jar
Synopsis: Improve jar file handling

Starting with JDK 8u45 release, the jar tool no longer allows the leading slash "/" and ".." (dot-dot) path component in zip entry file name when creating new and/or extracting from zip and jar file. If needed, the new command line option "-P" should be used explicitly to preserve the dot-dot and/or absolute path component.

See 8064601 (not public).

Area: deploy/webstart
Synopsis: jnlp app with nested "resource" section fails with NPE on load in jre8u40

A jnlp application, with nested <resources> tags within a <java> or <j2se> tag, can throw an NPE. The issue is now fixed. The <resources> tag should be used only if the <java> is actually used.

See 8072631 (not public).

Known Issues

Area: core-libs/jdk.nashorn
Synopsis: Finally blocks inlined incorrectly.

Nashorn has known issues where it incorrectly compiles try/finally constructs. For more information on this issue and a workaround, see Try/finally compilation issues wiki page.
