RI. 
> Following test reproduces the bug:
>     public void test_writeLByteBufferJ_ReadOnly_Exception() throws Exception {
>         File testFile = File.createTempFile("test", "tmp");
>         testFile.deleteOnExit();
>         FileChannel readOnlyFileChannel = new FileInputStream(testFile)
>                 .getChannel();
>         ByteBuffer writeBuffer = null;
>         readOnlyFileChannel.close();
>         try {
>             readOnlyFileChannel.write(writeBuffer, -1);
>             fail("should throw NullPointerException");
>         } catch (NullPointerException e) {
>             // expected
>         }
>         writeBuffer = ByteBuffer.allocate(1);
>         try {
>             readOnlyFileChannel.write(writeBuffer, -1);
>             fail("should throw IllegalArgumentException");
>         } catch (IllegalArgumentException e) {
>             // expected
>         }
>         try {
>             readOnlyFileChannel.write(writeBuffer, 0);
>             fail("should throw NonWritableChannelException");
>         } catch (NonWritableChannelException e) {
>             // expected
>         }
>     }
> The test passes against RI while fails against Harmony.
> I'll upload a patch to fix this problem soon.
> Thanks.
