All please check your configured update sites (preferences, Install/Update => Available Software Sites) to make sure only Indigo related sites are enabled (i.e. checked).
The following has worked for me:
- Clean Eclipse JEE 3.7.2 install
- About => Install New Software...
- Add..., http://download.jboss.org/jbosstools/updates/stable/indigo/
- Check Abridged JBoss Tools 3.3
- All is well
This install gives you everything but GWT, BIRT, Struts and source code.
The following is a list of enabled update sites in my install (note, the JBT related sites will appear automatically after the install):

Hope that helps,
