      Filed By : J2SE-SQA [###@###.###
      JDK : JDK1.4.2-b08
      Testbase : RegTest-test
      Platform[s] : Windows ME
      Falling test[s]:
              java/net/Authenticator/B4769350.java

      RegTest-test java/net/Authenticator/B4769350.java test hangs on our Windows ME machine.
      Such a behaviour is caused by the following circumstances:
      Regression test base for Mantis b08 contains the new file EmbeddedURLCallback.java containing
      the following bug in it:

          public void request (HttpTransaction msg) {
              URI uri = msg.getRequestURI();
              Request req = (Request) requests.get (uri);

      ...

              req.next();

              if (req.finished()) {
                  requests.remove (req);
              }
          }

      The requests map uses URIs as keys but remove is called for req.
      As a result, the server generates warnings on subsequent requests and does not handle it appropriately.

      Clients of java/net/Authenticator/B4769350.java sometimes produces more than two requests, but this is another issue.

      After I had changed the code as follows:

      requests.remove (uri);

      The test stopped hanging and produced sensible information meaning that all clients (c1, c2, c3, c4) were authenticated and retrived 'Hello's but some of them
      sent more than two requests:

      java.lang.RuntimeException: Authenticator was called 6 times. Should be 2
              at B4769350.except(B4769350.java:216)

              at java.lang.Thread.run(Thread.java:536)

      JavaTest Message: Test threw exception: java.lang.RuntimeException: Authenticator was called 6 times. Should be 2




      It also worth to apply the following fixes in sun/net/httptest/HttpServer.java:

      private String readLine (InputStream is) throws IOException {
      ...

      return new String (b, 0, l); // was "return new String (b)" which returned a large string padded with zeroes.
      }

      TEST_BASE_PATH="h:/java/regtest/test"

      TESTWITH=$JAVA_HOME
      TESTJAVA=$JAVA_HOME

      JTOPTS="-client"
      TESTVMOPTS="-client"

      CLASSPATH="$JT_HOME/classes;$JT_HOME/lib/javatest.jar;$JT_HOME/lib/jtreg.jar"

      export JAVA_HOME
      export JT_HOME
      export TESTWITH
      export CLASSPATH

      mkdir -p $WORK_DIR/scratch 2>&1
      mkdir -p $WORK_DIR/jtData 2>&1
      mkdir -p $REPORT_DIR 2>&1

      #rm $WORK_DIR/jtData/ResultCache.jtw 2>&1

      cd $WORK_DIR/scratch

      $JAVA_HOME/bin/java -cp $CLASSPATH $JTOPTS -DenvVars=TESTJAVAHOME=$JAVA_HOME,TESTVMOPTS=$TESTVMOPTS,DISPLAY=:0,windir=$windir,PATH=${SHELL%/*},TZ=,LC_ALL=en_US,LC_CTYPE=en_US,LANG=en_US,LPDEST= -DDISPLAY=:0 -DlocalHost="linux-18" -Dprogram=jtreg com.sun.javatest.regtest.Main -a -v default -batch -params -w "$WORK_DIR" -r "$REPORT_DIR" -t "$TEST_BASE_PATH" "$TEST_BASE_PATH/java/net/Authenticator/B4769350.java"

      --- script end ---
