Sorry attached files are quite big... however I had no time to seek for certain
part of FO document that causes the crash.
Comment 1 Adam Strzelecki 2005-12-27 15:14:25 UTC 
Created attachment 17285 [details]
Bug testcase... 2 FO files crashing FOP.
Comment 2 Manuel Mall 2005-12-28 03:36:02 UTC 
The first problem: CastClassException is already documented in bug #37743.

The second problem: NullPointerException is a new issue.

I'll have a go a fixing both of them (but it won't be pretty...).
Comment 3 Manuel Mall 2005-12-28 05:17:02 UTC 
The ClassCastException has been fixed as part of Bug #37743.

For the NPE fix see http://svn.apache.org/viewcvs?rev=359383&view=rev

I didn't manage to construct a small test case for the NPE. Any attempts to cut 
down the large param-tidy.fo to a reasonable size but still exhibiting the 
problem failed. I must be missing something. Any help / suggestions appreciated.
Comment 4 Glenn Adams 2012-04-01 06:40:52 UTC 
batch transition pre-FOP1.0 resolved+fixed bugs to closed+fixed
