Description Deepak Azad CLA 2011-07-05 09:03:18 EDT 
We already have quick assists to convert multiple catch blocks to a single multi-catch block and vice versa (bug 348061) and these could be made available as a cleanup. 

The clean-up options will go under 'Code Style' tab.

Before you implement this, I think bug 366453 and this should be fixed. Place your cursor on the second catch block and combine them via quick assist. 

Before:
try {
    new FileWriter("");
} 
catch (FileNotFoundException e) { } 
catch (IOException e) { }

Result:
try {
    new FileWriter("");
} catch (FileNotFoundException | IOException e) { }

This is a compiler error; it is not valid for catch blocks to have a union of types that are in a subtype/supertype relationship.

Adding Carsen, who did such cleanups (manual or maybe via Netbeans) in the past for the Eclipse code base.
