# Incompatibilities between Eclipse JDT 3.2 and 3.3

Eclipse changed in incompatible ways between 3.2 and 3.3 in ways that affect plug-ins. The following entries describe the areas that changed and provide instructions for migrating 3.2 plug-ins to 3.3. Note that you only need to look here if you are experiencing problems running your 3.2 plug-in on 3.3.

1. API contract changes to IClassFile

## 1. API contract changes to IClassFile

What is affected: Clients that call `IClassFile.getType()`.

Description: In Eclipse 3.2, the method `org.eclipse.jdt.core.IClassFile.getType()` threw a `org.eclipse.jdt.core.JavaModelException`. This is no longer the case in Eclipse 3.3! Note that this change has no impact on binary compatibility.

Action required: Clients calling `IClassFile.getType()` will have to fix possible 'Unreachable catch block for JavaModelException' compiler errors (only if this call is the only one throwing a `JavaModelException` in the try block). They also should verify for methods calling this API and throwing a `JavaModelException` that they still need to throw this exception.
