The tools.jar should have all the resources but it doesn't have the resources.
In case of the Japanese resources, tools.jar has only 3 resources as follows.

% jar tvf tools.jar | grep _ja | more
 83880 Thu Oct 26 01:36:54 JST 2000 sun/tools/javac/resources/javac_ja.properties
 41702 Thu Oct 26 01:35:56 JST 2000 com/sun/tools/javac/v8/resources/compiler_ja.properties
  8201 Thu Oct 26 01:35:56 JST 2000 com/sun/tools/javac/v8/resources/javac_ja.properties
%

The resources of the other tools are not contained in the tools.jar.
This problem occurs on Solaris only, both SPARC and IA.
