java.lang.UnsatisfiedLinkError is thrown when using jfxrt.jar and binaries (.so/.dll/.dylib files) in an OSGi environment on Mac OSX. In other words, the error occurs when jfxrt.jar and binaries are loaded through MANIFEST of another jar in an OSGi container. The problem is reproduced using JavaFX 2.0.2 (b08).

This is an OSGi-related issue because we do not see such an error when JavaFX is loaded from $CLASSPATH on Mac OSX.
This is a Mac-specific issue because we verified that JavaFX loads works in an OSGi container on Windows and Linux.

To reproduce the error,

(1) Download JDeveloper from:
     http://ide.us.oracle.com/download_adc/jdevadf/MAIN/nightly/JDEVADF_MAIN_GENERIC_120110.0013.6219/debug/jdevstudio.zip
     This version of JDeveloper includes/uses JavaFX 2.1.0 (b07).
(2) Expand jdevstudio.zip to /Desktop/jdevstudio/
(3) Open the terminal. Type the following to run JDeveloper
     /Desktop/jdevstudio/jdeveloper/jdev/bin/jdev -su -clean -J-Denable.webview=true -J-Duse.webview.on.mac=true
(4) Download attached sampleapp.zip. Expand it and open sampleapp.jws
(5) Double-click to open sample.jsf located under ViewController > Web Content.
(6) Design tab should fail to open the page because of the UnsatisfiedLinkError.
(8) java.lang.UnsatisfiedLinkError stack trace should appear in the terminal.
