Injecting a class compiled with a different Java version

Question

My bean gets a class injected which will be used in the (Java 6) owner class. However, the injected class is compiled in Java 7.

I currently get a Unsupported major.minor version 51.0 error, indicating this isn't possible. However, I've been wrong before. Any insight/sources on this subject?

Answer 1

What you are trying to do is actually not possible. If you have no more alternative than using that class, consider one of these two options:

• Is it possible for you to update your java production environment to a more recent version?
• Is it possible for you to decompile your injected java class and build it for java 6?
