The attached program and files will produce the following exception:

java.lang.ArrayIndexOutOfBoundsException: 8192
        at sun.nio.cs.ext.EUC_TW$Decoder.decodeArrayLoop(EUC_TW.java:2252)
        at sun.nio.cs.ext.EUC_TW$Decoder.decodeLoop(EUC_TW.java:2428)
        at java.nio.charset.CharsetDecoder.decode(CharsetDecoder.java:536)
        at sun.nio.cs.StreamDecoder$CharsetSD.implRead(StreamDecoder.java:442)
        at sun.nio.cs.StreamDecoder.read(StreamDecoder.java:182)

        at CharsetIOStreamClassTest.runDecodingTest(CharsetIOStreamClassTest.java:83)
        at CharsetIOStreamClassTest.main(CharsetIOStreamClassTest.java:43)

To compile/run the attached programs, do the following:

% javac CharsetIOStreamClassTest.java
% java CharsetIOStreamClassTest EUC_TW.b2c

The supporting classes will take the .b2c file and create a file 100,000 characters in size and will use this as the test data. The exception, however, will happen during the first read attempt from the stream.

This will not happen if you use the nio API or the String class. It only seems to happen when the io class is used.
