Mojarra 2.1.29 incompatible with JDK 1.6

Question

I upgrade my application to perffaces 5.1 and Mojarra javax.faces 2.1.29. Before I used JDK 1.7, at that time I was not getting any errors. To ensure compatibility with the client environment, I changed the JDK weblogic and My Eclipse runtimes to install JDK 1.6, and I get below the error. Has anyone encountered the same problem? Do I need to use the lower version of Mojarra 2.1.28 or 2.1.27 with JDK 1.6

Answer 1

This is really strange, but you're right. This is a JDK version issue. In my situation, I encountered the same error when using JDK 1.6.0-30, JSF 2.1.29 on Glassfish 3.1.2-11.

JDK 1.7.0-45, .
