I regret that I couldn't find an OCR parser to handle image/ocr-png.Please set the OCR_STRATEGY to NO_OCR or configure yourOCR parser correctly

Ok great. Yes please, DM me.

About the debug/trace issue, I think I solved it in the latest 2.10-SNAPSHOT.

For now, you can define a user setting FS_JAVA_OPTS set to -DLOG_LEVEL=debug.
