JNI_CreateJavaVM fails to recognise -X options such as -Xmx and friends. It
says:
libgcj: unknown option: -Xmx128M
I tracked it to this code in libjava/prims.cc:
else if (vm_args->ignoreUnrecognized)
{
if (option_string[0] == '_')
parse_x_arg (option_string + 1);
else if (! strncmp (option_string, "-X", 2))
parse_x_arg (option_string + 2);
else
{
unknown_option:
fprintf (stderr, "libgcj: unknown option: %s\n", option_string);
return -1;
}
}
else
goto unknown_option;
Notice how the -X options are only accepted if vm_args->ignoreUnrecognized is
true. This is contrary to the specification [1] which seems to say that
supported -X options should be recognized in all cases, whereas unknown -X
options should be ignored iff vm_args->ignoreUnrecognized.

Yeah, this logic looks bogus.

I'm trying, but my brand new Thinkpad insists on rebooting every time I build
gcc. Will have to investigate...

this patch is applied on the current trunk; the bug should be closed.
