> NPE on combination of ZWSP, NBSP and <fo:inline>

>                 Key: FOP-3035
>                 URL: https://issues.apache.org/jira/browse/FOP-3035
>             Project: FOP
>          Issue Type: Bug
>          Components: renderer/pdf
>    Affects Versions: 2.6
>         Environment: Linux SLES 11 running on Intel x86_64
>            Reporter: Paul Katz
>            Priority: Minor
>         Attachments: bad.fo, fop-config.xml, fop.log
>
>
> The following line in my XSL:FO reliably causes a NPE when generating a PDF:
>  
> {code:java}
> <fo:inline>&#x200B;<fo:inline>&#xA0;</fo:inline>x</fo:inline> {code}
> Removing any single element of this line makes the NPE go away:
>  
>  * The outer <fo:inline>
>  * {{The Zero-Width Space}}
>  * The inner <fo:inline>
>  * The Non-Breaking Space
>  * The "x" text
> (My actual document has more content within the outer <fo:inline>; I just removed everything else to provide the minimum content needed to reproduce the NPE.)
> The NPE is reported as:
>  
> {code:java}
> SEVERE: Exception
> org.apache.fop.apps.FOPException
> java.lang.NullPointerException
>         at org.apache.fop.cli.InputHandler.transformTo(InputHandler.java:296)
>         at org.apache.fop.cli.InputHandler.renderTo(InputHandler.java:116)
>         at org.apache.fop.cli.Main.startFOP(Main.java:183)
>         at org.apache.fop.cli.Main.main(Main.java:214)
> Caused by: java.lang.NullPointerException
> ... {code}
>  
> The complete FOP output is attached as fop.log.
> The complete input XSL:F0 is attached as bad.fo. The line of interest is near the bottom of the file. I have placed a comment above it listing several variations of the line with each element removed one at a time. Any of those alternatives prevents the NPE from occurring.
> My command line is:
>  
> {noformat}
> fop/fop-2.6/fop/fop -c WD/fop-config.xml -fo bad.fo bad.pdf 2>&1 | tee fop.log{noformat}
> My FOP config file is attached as fop-config.xml.
