Description
It seems that Batik is not thread save. We have several fixed/static SVGs that we include in XSL-FO and transform via Apache FOP. As long as we create the reports sequentially, such errors (see below) never occured so far. But when 2 reports are generated concurrently and both have (the same) SVG files included, a NullPointerException can occur:
---------------------------------------------------------------------------
084942921 SEVERE T61: SVG Errorfile:/C:/Programme/ddf/xml/images/V10271.svg:
The attribute "style" represents an invalid CSS declaration ("fill:#ef7b00; fill-rule:nonzero; stroke:none; stroke-width:1; stroke-linecap:butt; stroke-linejoin:miter; stroke-dasharray:none;").
Original message:

The result is, that the SVG image on one the report is displayed but with strange/different colors.
