[jira] [Updated] (FOP-3035) NullPointerException on combination of ZWSP, NBSP and
[ https://issues.apache.org/jira/browse/FOP-3035?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Paul Katz updated FOP-3035:
---------------------------
Description:
The following line in my XSL:FO reliably causes a NPE when generating a PDF:
{code:java}
<fo:inline>​<fo:inline> </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.
