Experience running Apache FOP on Apache Harmony

Project website: Apache FOP

2006-11-12, with Harmony snapshot r468731 on Windows

The "readme.fo" example from the FOP distribution ran just fine which is a very good sign. Problems started when running the same file with replaced default fonts which caused caused a problem because the TrueType loading code uses the "UnicodeBig" encoding. Changing that to "UTF-16BE" solved this particular problem. There's another use of "UnicodeBig" in the PDF library, where I cannot just replace the encoding with "UTF-16BE" because the FEFF marker needs to be generated.

Running "images.fo" showed that ImageIO will probably need a closer look. Furthermore, I got a "Can't open color profile" that I'll have to investigate more closely when I have time.

Anyway, this was just a quick test with a couple of test files and it shows that from now on I definitely have to keep on eye on FOP's compatibility with Harmony.

Keep up the great work, guys!

We've recently refactored the whole image loading part of FOP and the new framework now makes heavy use of ImageIO (as we've dropped support for JDK 1.3). I can build FOP using Harmony JDK but the unit tests fail because javax.imageio.ImageIO.getReaderMIMETypes is not implemented, yet. Maybe I'll find some time to look into the missing pieces.

BTW, while building FOP from scratch there's the following crash which doesn't occur when you run the build a second time. It is reproducible and always at the same location.

2010-07-27, with Harmony snapshot r979889 on Windows

The crash issue still occurs, the crashed module is either jitrino.dll or harmonyvm.dll (build-crash.dmp). The FOP can be built successful without any issue after a second try. However, there are some problems on unit tests. The major one is that junit-transcoder test suite cannot be completed (I killed the process after 20 minutes waiting junit-transcoder.dmp).

PS: The crash always occurs on Ubuntu 10.04
