      Current 1.5.0-beta b32a compiler compiles sources
      which contain static imports of different static methods
      with the same names and signatures. This behavior contradicts
      Public Review Draft of "Importing Static Members in the Java
      Programming Language":

      "If two or more single-static-import declarations in the same compilation
      unit attempt to import methods with the same simple name and signature,
      then a compile-time error occurs."

      This failure affects the following JCK 1.5 lang test:

      lang/PKGS/pkgs057/pkgs05701.html

      To reproduce this bug please run following test using
      script below, note that b33 compiler also contains
      this bug:
