I have the same problem, after Apple's Software Update suggested that a new update for Java 1.6.0 is available and I have told it to update. I have restarted the system just in case, but there is no difference.
I am using Eclipse Galileo with GAE SDK and Mac OS X 10.6.1. After the update, when I wanted to test a GAE Web app on the local test server, I get this error message: Dec 12, 2009 7:02:39 AM 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 $ jar tf /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/ Home/lib/plugin.jar java.io.FileNotFoundException: /System/Library/Frameworks/ JavaVM.framework/Versions/1.6.0/Home/lib/plugin.jar (No such file or directory) at java.io.FileInputStream.open(Native Method) at java.io.FileInputStream.<init>(FileInputStream.java:106) at java.io.FileInputStream.<init>(FileInputStream.java:66) at sun.tools.jar.Main.run(Main.java:206) at sun.tools.jar.Main.main(Main.java:1044) The plugin.jar is there as an alias but the Get INfo does not show that it is not pointing to any original. $ ls -l plugin.jar /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/lib/ plugin.jar -> /System/Library/Frameworks/JavaVM.framework/Resources/ Deploy.bundle/Contents/Home/lib/plugin2.jar plugin2.jar does not exist in the destination (Contents of the Deploy.bundle). Instead, we have plugin.jar in the directory. The plugin.jar is an alias and, in turn, pointing to: /System/Library/Frameworks/JavaVM.framework/Versions/A/Resources/ Deploy.bundle/Contents/Resources/Java/plugin.jar I probably can fix the Alias plugin2.jar to plugin.jar and it may all work. What do you suggest in order to fix it? I could use linux command "ln", but is that the way? The Apple Finder "Show Original" does not take me inside the Contents of a bundle.
