I think I've found the problem.

I recently changed libgcj so that command-line arguments are assumed
to be encoded in the locale's encoding.  This has the side-effect of
initializing java.lang.System earlier than was previously done.  This
means that the code in _Jv_RunMain which sets _Jv_Jar_Class_Path
doesn't affect the java.class.path property.

This is my theory anyway.  I don't have time right at the moment to
find out for certain.

In a way I'm glad we caught this since this code is currently too
fragile.  I'd like it to be more resilient in the face of changes like
mine; we should aim to be less dependent on a particular order of
initialization.  I'll try to write a patch soon, maybe today.

In the meantime if you want a workaround you can change JvConvertArgv
from this:

      *ptr++ = new java::lang::String (bytes, 0, len);

to this

      *ptr++ = new java::lang::String (bytes, 0, len,
                  JvNewStringLatin1 ("8859_1"));

I think that ought to avoid initializing System.

Another workaround would be not to use `jar' mode.
This works for me:

    CLASSPATH=paperclips.jar gij gnu.paperclips.boot.webappd --help
