Subject: Fix for unit test failure in transcoder tests (NullPointerException):
X-Git-Tag: fop-1_0~379
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=252a61b0a4fb8f5356c183df29df71d7f9e1bf4d;p=xmlgraphics-fop.git

Fix for unit test failure in transcoder tests (NullPointerException):
Have to pass the root PSGraphics2D to NativeTextHandler instead of the PSGenerator as this one hasn't been initialized in PSGraphics2D when the NativeTextHandler is built in AbstractPSTranscoder.

git-svn-id: https://svn.apache.org/repos/asf/xmlgraphics/fop/trunk@719629 13f79535-47bb-0310-9956-ffa450edef68
