Running Serviio over GCJ in a OpenMediaVault Home Media CE

Hello guys,
I have hacked my IOmega Home Media Cloud Edition with a OpenMediaVault distro.
The problem is that both Sun JDK/JRE and OpenJDK/JRE binary packages don`t work. They both yield "Segmentation Fault" regardless of the version I tried (Java 6 or 7).

I was having the same issue with FFMPEG and VLC. So I downloaded the source and built then (also the dependency libraries) and the now work just fine.
I was about to try the same (build) openJDK as well, but I realized that it needs a bootstrap JDK. Also tried IcedTea, but the same restriction applies, as it needs ANT as well. Cross-compiling those to my ARM (which is a NAS 7820 http://iomega.nas-central.org/wiki/Cate ... e_Media_CE) seems to be an Hercules Labour.

So I decided trying GCJ-JDK. And it works with no issues. But it looks like the Class Loader is a bit different. I don`t do any java programming on the last 5 years I think. Maybe you can help me.

Here is what I get:

  Code:

Apparently it is not looking properly at /root/serviio-1.0.1/lib/*. Then I tried the hard way. I expanded lib/*:

  Code:

Then I saw that org.serviio.util.JdbcUtils is on the same main JAR as org.serviio.MediaServer:

  Code:

root@hmnhdce-omv:~/serviio-1.0.1/lib# jar -tf serviio.jar | grep Jdbc
org/serviio/db/JdbcExecutor.class
org/serviio/util/JdbcUtils.class


Does anybody tried GCJ before and faced a similar issue?
