Subject ArrayIndexOutOfBoundsException

Hi everyone.

I'm stuck with a problem I don't understand. We have a tomcat server and after redeploying
our war file, we get this error:

java.lang.ArrayIndexOutOfBoundsException
	at org.apache.tomcat.util.buf.ByteChunk.append(ByteChunk.java:346)
	at org.apache.coyote.http11.InternalOutputBuffer$OutputStreamOutputBuffer.doWrite(InternalOutputBuffer.java:764)

	at java.lang.Thread.run(Thread.java:619)

Notice that there are no number on the first line and it is usually the case.
The code that is "responsible is:

private ServletOutputStream out;
private InputStream in;
...
in = new FileInputStream(tmp);
...
out = response.getOutputStream();
byte[] buf = new byte[8 * 1024]; // 8K buffer
int bytesRead;
while((bytesRead = in.read(buf)) > 0) {
	out.write(buf, 0, bytesRead);
}

The updated code didn't change anything in that Servlet so I really have no clue what happened.
It happens on tomcat 6.0.18 and 6.0.20. Java is 1.6.0_11.

Thanks for any help.

Best Regards

Geoffrey
