Jesse, Nejedláku, can you please look at this snapshot. Originally I thought that the problem is in FoD, but at the end FoD seems an innocent victim here.

#1 - you could change the Hudson$Logger to run outside of AWT. At least I think that Line$Show does not require to be in AWT.

#2 - there is >6s wasted while loading 
META-INF/services/com.sun.org.apache.xml.internal.dtm.DTMManager
the snapshot shows 22 ZIP files being open. Given that this is just sampling it might even be true that the classloading in platform was opening all the JARs. Seems to me that the classloading cache failed in this case.

latest report from 7.1 seems to work now, reopen if encountered again
