Jimmy,
Please add readFile.delete() and writeFile.delete() in the end of test
or .deleteOnExit() in any place. Files created by createTempFile are
not cleaned up automatically.
Ah yes, sorry for that, thanks!
So temp files may not controlled by OS itself even they are in temp
directory of OS?

Hi:
I find a conflict that RI does not behave as spec says in
java.nio.channels.FileChannel.transforFrom(ReadableByteChannel src,
long position,long count).
The spec says:"...Fewer than the requested number of bytes will be
transferred if the source channel has fewer than count bytes
remaining..."[1]. As expected, invoking this method with a count larger
than the number of bytes remaining in the ReadableByteChannel, RI should
return a number of bytes exactly transfered. But in fact, RI throws an
IOException. I run the test[2] on windowsXP SP2 with RI1.5.0_01 and
RI1.5.0_06, and on Linux(redhat 9) with RI1.5.0_02 and RI1.5.0_06, and
get the same result.
Currently Harmony behave well on this. I guess this is a bug of RI,
and Harmony implementation is good. If no objection, I suggest add this
test to Harmony.
Any opinions? Thanks!
[1] spec of FileChannel:
http://java.sun.com/j2se/1.5.0/docs/api/java/nio/channels/FileChannel.html
[2] the test:
public void test_transferFromLReadableByteChannelJJ_overflow()
throws Exception {
String content = "test content";
int length = content.length();
File readFile = File.createTempFile("testfile1", "tmp");
File writeFile = File.createTempFile("testfile2", "tmp");
FileOutputStream fos = new FileOutputStream(readFile);
try {
fos.write(content.getBytes());
} finally {
fos.close();
}
FileChannel fc1 = new FileInputStream(readFile).getChannel();
FileChannel fc2 = new FileOutputStream(writeFile).getChannel();
try {
long result = fc2.transferFrom(fc1, 0, length * 2);
assertEquals(length, result);
} finally {
fc1.close();
fc2.close();
}
}
