Tomcat 4 not working as standalone server

You have installed or upgraded your server to NetWare 6.5. Support Pack 7.
Tomcat doesn't work as standalone server.
Any HTTP request is rejected with:

HTTP/1.x 400 Bad Request
Server: Apache-Coyote/1.1
Transfer-Encoding: chunked

There is a bug in org.apache.coyote.tomcat4.CoyoteConnectorCoyote connector.
As a temporary workaround it is possible to use org.apache.catalina.connector.http.HttpConnector connector.

All connector settings are stored in this file:
SYS:\tomcat\4\conf\server.xml

Please refer to connector documentation.
