Build Identifier: Indigo release

when in the pom editor I managed to kill eclipse by trying to get the search to look for oracle jdbc drivers.

I attempted to do this by typing '*or' in the groupId (in the XML mode of the pom editor).

The ui locked up then after a while I got a message saying something bad had happened and I should restart eclipse.
In the log I get

Reproducible: Always

Steps to Reproduce:
1. open a maven project
2. open the pom in xml mode in the pom editor
3. add a dependency.
4. in the dependency add a group id element
5. inside the goupid element type *or
6. press ctrl+space (for auto completion

Notice the UI hangs here.
After approx 3 minutes you see a dialog
   "Unhandled event loop exception
   Java heap space"

Then there is a message about momory error and you are recommended to restart eclipse.

If wildcards are supported it shouldn't crash.
If they are not supported it should return zero results (i don't see anything in central with a groupid starting with *or
