Pavel Yaskevich commented on CASSANDRA-2256:
--------------------------------------------
Test for the problem:
{code}
public void testAssertOnRead() throws IOException
{
BufferedRandomAccessFile file = createTempFile("braf");
file.write(new byte[10]);
file.sync();
BufferedRandomAccessFile copy = new
BufferedRandomAccessFile(file.getPath(), "r");
copy.seek(15);
copy.read();
file.close();
copy.close();
}
{code}
This happens when you are trying to seek to position > file length on read-only
file and then read (because fileLength is cached, method isEOF() does not work
properly). I don't think that we should allow such seeks.
