Object.h (throwNoSuchMethodError): New method.

2005-12-08  Andrew Haley  <aph@redhat.com>

        * java/lang/Object.h (throwNoSuchMethodError): New method.
        * java/lang/Object.java (throwNoSuchMethodError): New method.
        * include/jvm.h (_Jv_ThrowNoSuchFieldError): Declare.
        * link.cc (_Jv_ThrowNoSuchFieldError): New.
        (link_symbol_table): Don't throw a NoSuchFieldError if a field is
        missing.  Instead, set the otable entry to zero.
        (link_symbol_table): If we don't find a nonstatic method, insert
        the vtable offset of Object.throwNoSuchMethodError() into the
        otable.
