Howard Gao commented on JBAS-6814:
----------------------------------
How to reproduce:
1. Build AS 5 CR1
2. run.sh -c default
3. deploy the servlet to default/deploy (test-servlet.war.zip)
4. run test client (httpunit-post.zip) at least 3 times. It needs http unit 1.7 to run.
5. observe the CPU status: The first time nothing happens, the second run will cause cpu
usage up to 50% (for a 2-core cpu), the third run will bring the cpu usage right to 100%.

Remy Maucherat commented on JBAS-6814:
--------------------------------------
The Servlet code is wrong, you should not "request" chunking, and actually all
the operations done there are simply wrong and inefficient. Lines which need to be removed
are marked with ">".
response.setHeader("JSESSIONID", session.getId());
response.setHeader("Content-Type",
"application/octet-stream");
response.setContentLength(-1);
response.addHeader("Transfer-Encoding","chunked");
response.setStatus(HttpServletResponse.SC_OK);
ServletOutputStream sos = response.getOutputStream();
sos.flush();
int num = 125;
byte somebytes[] = new byte[num];
for ( int i = 0; i < num; i++ ) {
somebytes[i] = (byte)i;
}
sos.write(somebytes);
sos.flush();
System.err.println("---------------finish");
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
request.getInputStream().close();
response.getOutputStream().close();
} catch (IOException e) {
e.printStackTrace();
}
}
Beyond that, I suppose you are saying that some chunked input causes an issue, this should
be looked into.
