> java.nio.channels.FileChannel.truncate, transferTo throw different exeptions from RI.
> Following tests reproduce the problems:
> public void test_truncateJ_Exception() throws Exception {
> File testFile = File.createTempFile("test", "tmp");
> testFile.deleteOnExit();
> FileChannel readOnlyFileChannel = new FileInputStream(testFile)
> .getChannel();
> try {
> readOnlyFileChannel.truncate(-1);
> fail("should throw IllegalArgumentException");
> } catch (IllegalArgumentException e) {
> // expected
> }
> }
> public void test_transferTo_Exception() throws Exception {
> File testFile1 = File.createTempFile("test", "tmp");
> File testFile2 = File.createTempFile("test", "tmp");
> testFile1.deleteOnExit();
> testFile2.deleteOnExit();
> FileChannel readOnlyFileChannel = new FileInputStream(testFile1)
> .getChannel();
> FileChannel readWriteFileChannel = new RandomAccessFile(testFile2, "rw")
> .getChannel();
> // first throws NonWritableChannelException even arguments are illegal.
> try {
> readWriteFileChannel.transferTo(-1, 10, readOnlyFileChannel);
> fail("should throw NonWritableChannelException.");
> } catch (NonWritableChannelException e) {
> // expected
> }
> try {
> readWriteFileChannel.transferTo(0, -1, readOnlyFileChannel);
> fail("should throw NonWritableChannelException.");
> } catch (NonWritableChannelException e) {
> // expected
> }
> }
> Both tests pass against RI while fail against Harmony.
> I'll upload to fix these problems soon.
> Best regards,
