After I sorted out setting ANT_HOME and FINDBUGS_HOME for my windows-i586 builds,
I find the build stopped cold, waiting for this process to return:

 2416 0:03 "javaw.exe" "-Dfindbugs.home=g:/martin/devtools/share/findbugs/findbugs-1.2.1" -Xmx384m -jar "g:/martin/devtools/share/findbugs/findbugs-1.2.1\lib\findbugsGUI.jar" "-version"

These Windows builds run over ssh->cygwin->MKS so there is nothing remotely
like a 'desktop' in the loop.

j2se/make/common/shared/Sanity.gmk line 113 looks like this:

_FINDBUGS_VER :=$(shell $(FINDBUGS) -version 2>&1 )


I would like to add -textui, so it looks like this:

_FINDBUGS_VER :=$(shell $(FINDBUGS) -textui -version 2>&1 )
