| /** |
| * Part 1: 6488669 |
| * 1) Http server that responds with an error code (>=400) |
| * and a chunked response body. It also indicates that |
| * the connection will be closed. |
| * 2) Client sends request to server and tries to |
| * getErrorStream(). Some data must be able to be read |
| * from the errorStream. |
| * |
| * Part 2: 6595324 |
| * 1) Http server that responds with an error code (>=400) |
| * and a chunked response body greater than |
| * sun.net.http.errorstream.bufferSize, 4K + 10 bytes. |
| * 2) Client sends request to server and tries to |
| * getErrorStream(). 4K + 10 bytes must be read from |
| * the errorStream. |
| * |
| * Part 3: 6993490 |
| * Reuse persistent connection from part 2, the error stream |
| * buffering will have set a reduced timeout on the socket and |
| * tried to reset it to the default, infinity. Client must not |
| * throw a timeout exception. If it does, it indicates that the |
| * default timeout was not reset correctly. |
| * If no timeout exception is thrown, it does not guarantee that |
| * the timeout was reset correctly, as there is a potential race |
| * between the sleeping server and the client thread. Typically, |
| * 1000 millis has been enought to reliable reproduce this problem |
| * since the error stream buffering sets the timeout to 60 millis. |
