We use Eclipse Galileo for all our projects. It has some problems with CPU load if you use Subclipse with large Java projects. But if you disable SVN decorators, it is ok (not perfect, but still better than the rest)...

We don't use every new Eclipse version for development because it needs a lot of time to check and change our projects. Don't believe that everything works out-of-the-box.

In the last days, we tried to update our Android plugin and... the new version does not support our "old" Eclipse version. We need at least Eclipse Helios... sh*t. We opted for the update, hoping that it does not take too much time.

Installation of Indigo and all our plugins was straight forward. But the "new" JDT have some side effects. It was not possible to compile JVx because KeyValueList and IdentityKeyValueList have a "Name clash". The problem details are described here. Not an Eclipse problem, a generics problem. But even that is not great.

After we set the compliance level for JVx from 1.5 to 1.6, it was possible to compile the project. Now we have Name clash warnings instead of errors. Not great but we can live with it. After we "solved" the first problem we had the next with our Web projects, because the Project Facets use Java 1.5 compliance level. But we learned that it is enough to set the level to 1.6 . To set the level from 1.5. to 1.6, we had to change the JRE for our Server environment(s) from 1.5 to 1.6. It is not a problem to use 1.6 but JVx is 1.5 compatible and it is not great to test without 1.5, but it is what it is.

Most of our projects are now migrated and again it was not funny to search "no" problems. We look forward to the next waste of time.
