Program exited with code 01.
(gdb)

it seems that libgcj-bc is disabled except linux (libjava/configure.host)
but SUPPRESS_LIBGCJ_BC_TRUE is enabled because it is default. and problematic
switches "-fzip-dependency java.zip -fzip-target java.jar" try to load
weeks.properties resource. then it invokes url classloader and find resource in
libgcj-.jar so results exception.

i tried to compile with --disable-libgcj-bc, but it has undefined symbol with
namespace org.xml (showing that there is no choice but to use libgcj-bc)
