Hi list, and happy new year to the geoserver users and developers !
I have a wms request that works fine when the output format is set to
either PDF (application/pdf) or PNG (image/png), but fails when trying
to set the output format to SVG (image/svg).
Any idea of what might be causing this ?
This is like saying “If I go to work by car or bike everything works, but using the train, something breaks, any idea what might be causing this?”.
The code writing out the format is very different in these three formats, PNG writes using Java2D, PDF using iText and SVG using Batik.
Geoserver version is 2.14.0.
Stack trace is here : https://pastebin.com/EHq0Lmau
From the trace I see:
-
Caused by: java.lang.NullPointerException
-
at org.apache.batik.svggen.ImageHandlerBase64Encoder.encodeImage(ImageHandlerBase64Encoder.java:157)

Making a guess, maybe the style is pointing to an image that cannot be located, and SVG will throw an NPE instead
of silently skipping it? Or, if this is the actual code (lines number might not match, but it seems they do) it could be
that for some reason Batik is not finding a PNG encoder (the writer variable), but I would not know why or how:
https://github.com/apache/batik/blob/trunk/batik-svggen/src/main/java/org/apache/batik/svggen/ImageHandlerBase64Encoder.java#L152
This would need someone running a debugger inside the Batik encoding (and possibly initialization of that registry) and figure out
what happened. A first step would be to open a bug report on Jira with reproducible steps (including data and style needed).
Also, make sure you’ve tried the generation on the latest stable version (2.14.1) as we have been upgrading Batik a few times recently.
Cheers
Andrea
