Today, when I tried upgrading the JDK/VM that Google App Engine is using from Eclipse Galileo to Java 6 in Mac OS X, I got the error below:

com.google.appengine.tools.development.agent.impl.BlackList initBlackList
SEVERE: Unable to read a jre library while constructing the blacklist. Security restrictions may not be entirely emulated. /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/lib/plugin.jar
The server is running at http://localhost:8888/

Fortunately, after a bit of searching I found a quick fix.

cd /System/Library/Frameworks/JavaVM.framework/Resources/Deploy.bundle/Contents/Home/lib/

sudo ln -s plugin.jar plugin2.jar
