What steps will reproduce the problem?

1. Install Lombok
2. Run Eclipse Ganymede or Eclipse Galileo
3. Try launching the Help Contents.

What is the expected output? What do you see instead?

Expected output is, of course, to have the help launched.
Instead, a 500 error code is thrown by Jetty, the underlying server that
runs the help.

What version of the product are you using? On what operating system?

Eclipse 3.4 and 3.5, both on Windows

Please provide any additional information below.

It seems that lombok try to modify either the jetty or help jars at
launch, which is an unexpected behaviour. The
org.eclipse.core.runtime.IStatus is the class that is impacted.

Good find, Olivier. The help is built from JSP files, which need to be compiled, which eclipse does with its own
parser, which has been instrumented by lombok. Lombok is indeed at fault.

Will look at fixing it later. For now marking it as valid.

I wish java itself was developed when lombok already existed, because the ClassCastException isn't being
THROWN, it's being passed someplace which isn't legal and is causing an IllegalArgumentException, which
prints the toString() of the ClassCastException, which for whatever reason doesn't have a useful toString().
D'oh!

The stack trace generated is:

This has been fixed in commit 72cc800 and will be rolled out in v0.8.4.

Some changes to lombok that will go live in v0.9 may cause a recurrence of this bug, though I tested it, and it
doesn't seem to be occurring.
