That's the way I patched my CDT with a bugfix for https://bugs.eclipse.org/bugs/show_bug.cgi?id=271623

Just copying a plugin with a new version won't work. The eclipse plattform keeps track of the jars to use. AFAIK, you have to create a new deployable feature version and update eclipse with the new one. To much work for me -> I prefer #1 ;)

See my comment above.
