How does the Java API differ between NDDS 3.x and RTI Connext 4.x?

Note: Applies to NDDS 3.x and RTI Connext 4.x and above.

The Java API in RTI Connext 4.x and above complies with the DDS standard and is much more consistent with its C and C++ interfaces, but is very different from the Java API in NDDS 3.x.
