trang fails to run properly

[mhosken]

Binary package hint: trang

trang seems to be built wrongly:
On jaunty.

When run I get this error:
trang lift.rng lift.xsd
Exception in thread "main" java.lang.NullPointerException
   at org.relaxng.datatype.helpers.DatatypeLibraryLoader$Service$Loader2.getResources(libgcj_bc.so.1)

   at com.thaiopensource.relaxng.translate.Driver.doMain(trang)
   at com.thaiopensource.relaxng.translate.Driver.main(trang)

and when I pdebuild the source package I get the warning:
dpkg-shlibdeps: warning: /usr/lib/libgcj_bc.so.1 has an unexpected SONAME (libgcj.so.90)

(among other warnings)

I get the same thing.

Was it incorrectly compiled to use the link time only lib? Looks like it:
$ ldd /usr/bin/trang
 linux-vdso.so.1 => (0x00007fff6b7ff000)
 libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00007fe7632ad000)

However, the following workaround doesn't work:

I'm seeing something that appears essentially the
same in 9.04 with an xml to dtd conversion. If I were
using java directly with jars, I would expect to see this
with an incorrect classpath specification.

Moreover, no source for ubuntu's binary package
"trang" seems to be available.

Also I see:

> apt-cache policy trang
The "trang" package looks old.

trang:
  Installed: 20030619-6.1
  Candidate: 20030619-6.1

I recall that in the past I would get different results using
these guys (James Clark's "dtdinst" and "trang") with Sun's
java engine under Solaris vs. under Debian. In those days
I was never able to get them to work with gcj. As I recall,
that seemed to be because things were missing in the
gcj libraries.
