Static build failing to load classes

Wed Nov 16 22:56:00 GMT 2005

I'm trying to do a static build with today's gcj code. With a trivial java
program,
it crashes, apparently unable to load a class I'm reasonably sure is
included
in the binary. Is this a known problem?
My compile command:
/var/local/gcc/tip_20051115/bin/gcj -static --main=Hello -g -o Hello.bin
Hello.java
My GCJ and linux:
 gcj (GCC) 4.1.0 20051116 (experimental)
 (revision 107090 from SVN, checked out 2005年11月16日)
 Linux version 2.6.8.1-10mdk
Here's the trivial source I'm trying to run with the interpreter. It works
OK when compiled to a dynamic executable, but not with a static build.
 public class Hello
 {
 public static void main (String[] args)
 {
 System.out.println("hello");
 }
 }
>From the backtrace below, it seems like java.net.URLClassLoader.findClass
can't find
gnu.java.locale.LocaleInformation.class. I did "nm --defined-only Hello.bin
| grep LocaleInformation$"
and got:
 08490f54 d _catch_classes_gnu.java.locale.LocaleInformation
 08490f40 d _MT_gnu_java_locale_LocaleInformation
I think that means the gnu.java.locale.LocaleInformation class is included
in the binary, and therefore should have been loaded by the class loader.
Here's the backtrace for Hello.bin.
