A DESCRIPTION OF THE PROBLEM :
We have an JMS message (TEXT), from COBOL, using comp-3.
We try to get the byte[] from the String, in order to recover our hexa values.

We have an issue while decoding a byte (0x15) with the Cp1147 encoding.
The byte is decode as 0x25 instead of 0x15.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Creating a byte array containing the 0x15 value.
Create string from that byte array, using CP1147.
Create a second byte array from the string, using C1147.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
We expect the byte to be the same (0x15)
ACTUAL -
The byte's value is 0x25.

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
@Test
public void testEncoding1147() throws UnsupportedEncodingException{
byte[] bytes = new byte[]{ (byte)0x15, (byte) 0x7B };


printByte(bytes);


System.out.println("##################################################");


String strBytes1147 = new String(bytes, "CP1047");
System.out.println("strByte Cp1147 ["+strBytes1147+"]");
byte[] bytesDecodes = strBytes1147.getBytes("CP1047");

printByte(bytesDecodes);

System.out.println("##################################################");

Assert.assertEquals("Size of bytes tables not corresponding", bytes.length, bytesDecodes.length);
for(int i = 0; i < bytes.length; i++ ){
Assert.assertEquals("byte N° ["+i+"] not matching", bytes[i], bytesDecodes[i]);
}
}


private void printByte(byte[] bytes){
StringBuilder sb = new StringBuilder();
for (byte b : bytes) {
    sb.append(String.format("%02X ", b));
}
System.out.println(sb.toString());
