Description myquestions 2003-01-11 10:28:37 UTC 
The following conditions cause what appears to be an infinite loop in the fop
processor:
-  fo:flow defined with multiple columns
-  fo:block #1 contains just one single external graphic
-  fo:block #2 (follows fo:block #1) has attribute span="all"

I will include the .fo file.
I am running JDK1.3.0_02.
The command used:   fop columnbug.fo columnbug.pdf

Please add your own image and call it columnbug.jpg.
Any jpeg image should do.

Works with latest Trunk (rev 584703), and probably in FOP 0.94, on JVM 1.5

This should either be closed, or tested with JVM 1.3 (depending on decision for
JVM support)

batch transition to closed remaining pre-FOP1.0 resolved bugs
