InvocationTargetException when running applet locally

I wasn't using JNLP so I don't know if JNLP versioning was the relevant part of the release notes.  The part about " Non-JNLP trusted applet fails to load using the file:\\ URL", however, seemed highly relevant.  The recommended approach was " Use a JNLP file to launch the applet" and I tried that modeled after the information at http://www.oracle.com/technetwork/java/javase/index-142562.html but that didn't work.  However, I've never used JNLP before so it is possible that I made some error in using JNLP.  

Someone suggested that the problem relates to compression, but using "jar cfm0" instead of "jar cfm" didn't help, though it did produce an uncompressed JAR file.

I'll try again to file the bug report, but 7update45 fails in every environment I've tried except using Vista and turning off the next generation Java plugin, and even that works in Internet Explorer, not Firefox.  And on Windows 8, even using 8build111 fails with Internet Explorer, but works with Firefox.  

Things this brittle make me nervous. It would be good if there were some effort at Oracle to get this fixed quickly or provide more details about workarounds.

I think this is a known issue. There is a workaround documented in the JDK 7u45 release notes, can you try it out? See "JNLP applet fails to load if using JNLP versioning.":
