[jira] [Commented] (BATIK-1313) NPE in DefaultXBLManager
[ https://issues.apache.org/jira/browse/BATIK-1313?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17373444#comment-17373444 ]
Erich Schubert commented on BATIK-1313:
---------------------------------------
The same code works fine using
org.apache.batik.anim.dom.SVGDOMImplementation
instead of
org.apache.batik.anim.dom.SVG12DOMImplementation
so this is definitely connected to some SVG 1.2 code, although I do not use any particular SVG 1.2 features.

> Looks like the imports may sometimes be null. I do not have a test case, it likely may be due to threading. Either way, the code should be more robust here and do a null check.
