I just migrated from java6 --> java7.
During compilation, I get a lot of errors pertaining to generic typing on
classes from felix, version 4.0.2; I've put the compilation errors at the
bottom of this message.
Here's something I found that suggests that the felix source might not be
compiled with java 1.7?
https://github.com/osgi/bindex/issues/11
The Felix framework targets jsr14, which allowed it to take advantage of
generics, but still have byte code compatible with JDK 1.4. If you are
compiling against the framework JAR file in Java 7, then you need to
recompile the framework using Java 7 (i.e., get rid of target jsr14). Of
course, you could just get an OSGi API JAR compiled for Java 5 or above,
since you likely don't need to compile against Felix framework internals...
The coming framework 4.2.0 release will target Java 5 instead of jsr14,
so this issue should go away in the future.

Any thoughts?
