problem when testing tomcat

[tlm6291 <tl...@163.com>]

Hello:
    I am new in learning Tomcat.
 
    In turn, I download tomcat source code , build it with Apache-Ant , and test it with JUnit. I use the following commands to build and test Tomcat
         ant test
 
    It seams the test fails as I got the following result:
         BUILD FAILED
          E:\work\apache-tomcat-7.0.20-src\build.xml:1063: The following error occurred while executing this line:
          E:\work\apache-tomcat-7.0.20-src\build.xml:1125: Some tests completed with an Error. See E:\work\apache-tomcat-7.0.20-src/output/build/logs for details.
          Total time: 21 minutes 24 seconds
 
    Then I found the following tests failed
           org.apache.tomcat.util.net.TestSsl
           org.apache.tomcat.util.net.TestCustomSsl
 
    The following is my test environment:
          System:   Windows XP sp3
          JDK:      1.6.0-u21
          Apache-Ant:    1.8.2
          Tomcat:   7.0.20
         
     My questions are:
          1. Should all the test had to pass?
          2. What's the use of the java classes in the path of "apache-tomcat-7.0.20-src\test"
          3. Also I had tested Tomcat under JDK-1.7.0,  is Tomcat7.0.20 compatible with JDK1.7 ?
 
    Thank you very much and best regards!
