Java SE Development Kit 7

The Java SE Development Kit 7 lets you develop and deploy Java applications on desktops and servers, as well as in today's demanding embedded environments. Java offers the rich user interface, performance, versatility, portability, and security that today’s applications require.

New Features and Changes

• New Command-line option to Identify Use of Deprecated Mechanisms - The endorsed-standards override mechanism and the extension mechanism are deprecated in JDK 8u40 and may be removed in a future release. There are no runtime changes. Existing applications using the 'endorsed-standards override' or 'extension' mechanisms are recommended to migrate away from using these mechanisms. To help identify any existing uses of these mechanisms, the -XX:+CheckEndorsedAndExtDirs command-line option is available. It will fail if any of the following conditions is true:
  • -Djava.endorsed.dirs or -Djava.ext.dirs system property is set to alter the default location; or
  • ${java.home}/lib/endorsed directory exists; or
  • ${java.home}/lib/ext contains any JAR files excluding the ones that JDK ships; or
  • any platform-specific system-wide extension directory contains any JAR files.
  The -XX:+CheckEndorsedAndExtDirs command-line option is supported in JDK 7u80 and later releases.

Bug Fixes

• Area: tools/jar
  Synopsis: Improve jar file handling
  Starting with JDK 7u79 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.
