Fop fails to resolve embedded fonts after update from 2.6 to 2.7

Hi!

I've googled for breaking changes of an apache fop 2.6 -> 2.7 update, but I
have got nowhere.

After a fop update from 2.6 to 2.7, my application fails to resolve
embedded font files from the jar classpath. A resolver is registered at
"new FopFactoryBuilder(new File(".").toURI(), resolver)",
"transformerFactory.setUriResolver(resolver)" and
"transformer.setURIResolver(resolver)" but get's not called on embedded
fonts. However, this stacktrace is printed:

SEVERE: Failed to read font file myProject/fonts/myFont.ttf (No such file
or directory)
java.io.FileNotFoundException: <basePath (from new
File("."))>/myProject/fonts/myFont.ttf (No such file or directory)

How can I reenable font resolving in fop 2.7?

Thanks
