# Incompatibilities between Eclipse JDT 3.8 and 3.9 (Kepler)

Eclipse changed in incompatible ways between 3.8 and 3.9 in ways that affect JDT plug-ins. The following entries describe the areas that changed and provide instructions for migrating 3.8 plug-ins to 3.9. Note that you only need to look here if you are experiencing problems compiling or running your 3.8 plug-in on 3.9.

1. SDK ships only one org.junit plug-in (4.11)

## 1. SDK ships only one org.junit plug-in (4.11)

What is affected: Clients that require the `org.junit4` bundle, or `org.junit` with an upper version bound

Description: The `org.junit` bundle has been updated to JUnit 4.11. The `org.junit4` compatibility bundle has been removed, and `org.junit` version 3.8.2 is no longer shipped with the Eclipse SDK. Note that JUnit 4 still contains the JUnit 3 APIs. If you need `org.junit_3.8.2` back for whatever reason, you can still get it from Orbit.

Action required: Clients that require `org.junit4` should switch over to `org.junit`. Your `Require-Bundle:` entries should just point to `org.junit;bundle-version="4.11.0"` (or an earlier version, if you like).
