Summary: NullPointerException in
LineHeightPropertyMaker.java:57
Product: Fop
Version: 0.95
Platform: PC
OS/Version: Linux
Status: NEW
Severity: major
Priority: P2
Component: general
AssignedTo: fop-dev@xmlgraphics.apache.org
ReportedBy: dominik.stad...@gmx.at
We use FOP to generate PDF reports. On one machine it started to fail with the
following error with no apparent reason. It seems this is an intermittent
problem as it did work before without code change. Also the same code runs fine
on other machines.
We will restart the machine soon and see if it keeps appearing on this one or
if it really is gone again after restarting.
I am attaching the XSL-FO that is used here, but generating this on another
machine works fine so it doesn't seem to be the cause.
