Hi Andrew,

6959197: When building with JAVAC_MAX_WARNINGS=true, the build fails in 
sun/nio/cs due to the use of -Werror

(1)sun/io/ByteTocharISO2022JP.java
    #129,  #151

    if ((byte1 & (byte)0x80) != 0){

        if ((byte2 & (byte)0x80) != 0){


(byte) casting is not necessary as well?

(2)sun/io/ByteToCharJISAutoDetect.java

   we should (if I did not miss anything) simply change the
   sun/nio/cs/ext/JISAutoDetect.getByteMask1|2 to static, then no longer 
need to
   have an instance in ByteToCharJISAutoDetect.

(3)sun/nio/cs/ext/EUC_JP_LINUX.java

     encoderJ0208 no longer needed? 

   decodeMappingJ0208.start = 0xa1;
   decodeMappingJ0208.end = 0xfe;

      seems like we should simply replace decodeMappingJ0208.start/end 
with start/end
      and the decodeMappingJ0208 is no longer necessary as well.

(4)

   again, it might be better to do something as below. The EUC_JP_xyz 
are something need to
   be re-written/-re-organized when we have time.

  short[] j0208Index1 = JIS_X_0208_Solaris_Decoder.getIndex1();
  String[]j0208Index2 = JIS_X_0208_Solaris_Decoder.getIndex2();

    int start = 0xa1;
    int end = -0xfe;

 100     protected char decodeDouble(int byte1, int byte2) {
 101             if (byte1 == 0x8e) {
 102                 return decoderJ0201.decode(byte2 - 256);
 103             }
 104 
 105             if (((byte1 < 0)
 106                 || (byte1 > j0208Index1.length))
 107                 || ((byte2 < start)
 108                 || (byte2 > end)))
 109                 return REPLACE_CHAR;
 110 
 111             char result = super.decodeDouble(byte1, byte2);
 112             if (result != '\uFFFD') {
 113                 return result;
 114             } else {
 115                 int n = (j0208Index1[byte1 - 0x80] & 0xf) *
 116                         (end - start + 1)
 117                         + (byte2 - start);
 118                 return j0208Index2[j0208Index1[byte1 - 0x80] >> 4].charAt(n);
 119             }
 120         }

    encoderJ0208 is no longer needed.

(5) sun.nio.cs.ext.PCK.java

    JIS_X_0208_Solaris_Encoder jis0208 is no longer needed
