Strange error messages on the console

[Joern Huxhorn]

Hi everyone.

I just tested my app on Oracle Java 7 U5 & OS X 10.7 and it is printing strange messages:

<Error>: CGContextGetCTM: invalid context 0x0
<Error>: CGContextSetBaseCTM: invalid context 0x0

(those show up multiple times)

To reproduce, just download http://sourceforge.net/projects/lilith/files/lilith/0.9.42/lilith-0.9.42.1-all.jar/download and start it with

java -jar lilith-0.9.42.1-all.jar

Any idea what is causing this? Is there a hidden problem in my app or is this a Java on OS X bug? Everything else seems to work as expected.

Cheers,
Joern.
