I noticed a serious issue in 1.0 runtime deployment while
  trying out the demos from javafx.com.

  The problem is that the D3D-accelerated Decora dll
  isn't being found, so software rendering is used for
  applets.

  For example, launching this:
    http://www.javafx.com/samples/InterestingPhotos/index.html
  gives the following in the java console:
Applet2ClassLoader: Policy.getPolicy() took 0 ms
basic: JNLP2ClassLoader.getPermissions() X
basic: JNLP2ClassLoader.findLibrary: Looking up native library: Decora-D3D.dll
basic: Native library Decora-D3D.dll not found
basic: JNLP2ClassLoader.getPermissions() ..
Applet2ClassLoader: Policy.getPolicy() took 0 ms
basic: JNLP2ClassLoader.getPermissions() X
basic: JNLP2ClassLoader.findLibrary: Looking up native library: Decora-SSE.dll
basic: JNLP2ClassLoader.findLibrary: native library found: C:\DOCUME~1\tdv\LOCALS~1\Temp\.java_jnlp_applet_nativelib_cache.tdv\tmp42697\Decora-SSE.dll
Calling synthesizeWindowActivation(true) for applet 1
  Called PluginEmbeddedFrame.requestFocus()
Calling synthesizeWindowActivation(true) for applet 1
  Called PluginEmbeddedFrame.requestFocus()

  This happens on all demos.

  Same thing with hudson build demos using production servers
  for the runtime:

This used to work fine with hudson-based builds.
