----------------------------------
Summary: Null pointer exception when transforming to PDF with FOP
2.0
Key: FOP-2511
URL: https://issues.apache.org/jira/browse/FOP-2511
Project: FOP
Issue Type: Bug
Affects Versions: 2.0
Environment: OS X 10.9.5 . Tested both with JDK 1.7.0_45 and JDK 1.6.0
Reporter: Johan Persson
Priority: Critical
When trying to transform to PDF I'm experiencing a NULL pointer exception. See
below. The same fo-file used as source works without problem with FOP 1.1
The source for the fo-file is a set of DocBook 5 sources transformed using
XSLTproc. The fo-file that produces the crash can be found at my Google-Drive
