The Scala 2.7.7 distribution

What is new?

This release includes:

• A fix for an issue in the Actors library that could lead to problematic growth of the underlying thread pool. The old FJTaskRunner was replaced with a backport of ThreadPoolExecutor. Intermittent termination of the thread pool is handled more gracefully.
• A fix for issue #2380 [2], which was causing problems to some users of the Scala IDE for Eclipse running on a 1.5 VM.
• An AJDT compatibility fix addressing ticket #2327 [3], related to the installation of the Scala IDE for Eclipse.
• A fix for issue #2392 [4], "Finally clauses don't work correctly if they throw an exception".
• An improved fix for bugs #373737 [5], #1896 [6], #1930 [7] (problem with pickler/unpickler), addressing a problem with the Lift framework.
• A fix for issue #1535 [8] (problem with inherited lazy val).
• A fix for the IzPack uninstaller issue #1433 [9], which may cause some empty subdirectories to be erroneously purged from the installation directory on *nix systems (Windows systems are not affected).
• Support for automatic privilege elevation on Vista and Windows 7 for the installer, and other minor improvements.
