Ah, much better, thanks. Here are the revised times (BTW, that's

Note that classpath sources need a tiny hack to keep ecj from crashing.
But that looks like an upstream Eclipse bug, since I could reproduce it
running ecj with java-1.5.0-sun.
Andrew, I don't suppose you still need oprofile data (or are there other
places where gcjlib:// loading might be a problem)?
The ecj-native times still look somewhat slow. Back in the RHUG days, a
gcj-compiled ecj was faster than jikes at building classpath. Perhaps
the BC-ABI stuff is slowing us down a bit.
