> Key: FOP-2943
> URL: https://issues.apache.org/jira/browse/FOP-2943
> Project: FOP
> Issue Type: Bug
> Components: fo/block
> Affects Versions: 2.5
> Environment: debian buster
> Reporter: Attila Soki
> Assignee: J Frank
> Priority: Major
> Attachments: fop-block-npe.fo, patch-FOP-2943.diff
> 
> 
> The above block causes NullPointerException when written as shown, without white \
> spaces between the tags: {{<fo:block><fo:inline>block1</fo:inline><fo:character \
> character=" "/></fo:block>}} adding a space between <fo:charater.. /> and \
> </fo:block> solves the problem (see testcase: fop-block-npe.fo) \
> {{<fo:block><fo:inline>block2</fo:inline><fo:character character=" "/> \
> </fo:block>}} {{a non white space fo:character solves the problem too}}
> {{<fo:block><fo:inline>block3</fo:inline><fo:character character="-"/></fo:block>}}
> {{could be related to FOP-2147}}
> The exception:
> java.lang.Exception: Invoke failed: \
> [[o:TransformerIdentityImpl]]->;transform((i:Source)[o:StreamSource], \
> (i:Result)[o:SAXResult]). Cause: java.lang.NullPointerException VM: \
