Example 87 with DefaultServlet

use of org.apache.catalina.servlets.DefaultServlet in project tomcat by apache.

/*
     * https://bz.apache.org/bugzilla/show_bug.cgi?id=58624
     *
     * This test requires three breakpoints to be set. Two in this file (marked
     * A & B with comments) and one (C) at the start of
     * WsRemoteEndpointImplServer.doWrite().
     *
     * With the breakpoints in place, run this test.
     * Once breakpoints A & B are reached, progress the thread at breakpoint A
     * one line to close the connection.
     * Once breakpoint C is reached, allow the thread at breakpoint B to
     * continue.
     * Then allow the thread at breakpoint C to continue.
     *
     * In the failure mode, the thread at breakpoint B will not progress past
     * the call to sendObject(). If the issue is fixed, the thread at breakpoint
     * B will continue past sendObject() and terminate with a TimeoutException.
