Build Identifier: Not sure how I did it, but the content assist popup suddenly got frozen, and Eclipse doesn't respond anymore. The cursor is still blinking though. Eclipse is now eating up one of my CPUs, and a threaddump shows the following: "main" prio=10 tid=0x09bba000 nid=0xd36 runnable [0xbf9de000] java.lang.Thread.State: RUNNABLE at
