> 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

> 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: 1.7.0_45@[http://java.oracle.com/]" at:
