Netx 0.4.1
Version 0.4.1 fixes a download bug that caused some applications not to run on some systems.

Improvements since previous version:
  • Delegate to original Policy object to run under Web Start
  • Command line switch to set update policy in seconds.
  • Update checks based on a policy (time since last check).
  • Stops threads in an application (before just closed its windows)
  • AWT thread's context classloader set to app's classloader when app window active
  • API to launch app in external copy of netx (javaw must be in path)
  • Launches app if BasicService.showDocument URL ends in .jnlp
  • Basic support for opening web pages with showDocument.
  • Fallback to cached version if update check fails (before just exited)
  • Can stop apps that use JFrame.EXIT_ON_CLOSE mode.
  • New threads should be created in app's ThreadGroup
  • Can tell tracker to start downloading without blocking.
  • Can listen to tracker for completion of downloads
  • Tracker synchronization uses finer grained locking and locks for less time
  • Code started from thread in its own thread group (was in system thread group b/c of bug).
  • Can set default JNLPFile view to a specific os, arch, locale
  • Removed part feature from resource tracker
  • IconDesc picks the best icon not just the first
  • Fixed non-threadsafe code in JNLP services
  • Fixed download progress freaking out bug

  • Cache checks for new versions with option to disable update checks
  • Proper security permissions for system properties from JNLP file.
  • Codebase defaults to file's location (its directory)
  • Non-resizable applets (is this a good thing??)
