Description

Name: asR10013			Date: 04/27/2000


    The following code demonstrates unexpected behavior of the JVM. 
Exception java.lang.InternalError is thrown as a result of method 
String.getBytes invocation on line 4.

------------------------ test.java -----------------------------------
1 class test {
2     public static void main(String args[]) throws Exception {
3 	String s = "\u3000";
4 	byte[] ba = s.getBytes("Cp933");
5     }
6 }
-------------------------- output ------------------------------------
$ java -version
java version "1.3.0beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0beta-b01)
Classic VM (build 1.3.0beta-b01, green threads, nojit)
$ java test
Exception in thread "main" java.lang.InternalError: Converter malfunction: sun.io.CharToByteCp933

EVALUATION To encode this single character in Cp933 requires 4 bytes - 2 bytes plus a shift-in and shift-out character. getMaxBytesPerChar() needs to be changed to return 4 since this is the max byte occupation for a general single char for this encoding. --Ian.Little@Ireland 10/19/2000
