Obtain fresh copy of Eclipse with Java EE Support 2. Install Plugin Help -> Install ... 3. After Installation is finished click "Apply Changes Now"
The exception seems to be in ServerCore (wst.server) on this line: if (rt[i].getId().equals(cf[j].getAttribute("id"))) { This is already a bit strange, since it seems it'd be occurring during the "removal" of an extension, and not an addition. So I am already quite confused as to how the flow of execution could even enter this code. If you download a stock eclipse and then add an extension, it should never enter the 'removal' section. I think Angel should look into this most-likely.
