[jetty-dev] hanging JGit HTTP tests using Jetty 8.1.3.v20120416

[Matthias Sohn <matthias.sohn@xxxxxxxxxxxxxx>]

we upgraded the JGit HTTP tests which used Jetty 7.1.6 so far to

Jetty 8.1.3.v20120416 coming with Juno [1]. These tests start a Jetty server

with some JGit servlets from the JUnit's setup method and then send git 

commands over HTTP in order to test jgit's HTTP transport protocol 

implementation.

On some machines (actually hudson.eclipse.org running on SLES and

Dani's windows PC) these tests hang when run using Jetty 8.1.3.v20120416.

Dani captured a thread dump of the latter case [2] [3]. The jgit test sends

a request similar (recorded on Mac where the tests do not hang) to:

GET /git/test1338294501573_0.git/info/refs HTTP/1.1
Accept-Encoding: gzip
Pragma: no-cache
User-Agent: JGit/unknown
Accept: */*
Cache-Control: no-cache
Host: 127.0.0.1:65167
Connection: keep-alive

and hangs waiting for a response. It seems the request doesn't

reach any of the JGit servlets. This didn't happen with the exact

same tests run on Jetty 7.1.6.

The expected response for the above request should look similar to

HTTP/1.1 200 OK
Expires: Fri, 01 Jan 1980 00:00:00 GMT

Any idea what could be wrong ?

Any hints how to trouble shoot this problem ?

I also asked webmaster to get a thread dump on hudson [4] but this isn't 

available yet
