[jira] [Created] (FOP-2943) NPE when fo:block contains inline and charater tags and character is a white space

[Attila Soki (Jira)]

Attila Soki created FOP-2943:
--------------------------------

             Summary: NPE when fo:block contains inline and charater tags and 
character is a white space
                 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
         Attachments: fop-block-npe.fo

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:

With FOP version 0.94 works.
