      Filed By : J2SE-SQA [###@###.###
      JDK : JDK1.5.0-b05
                        (passes with JDK1.5.0-b04, JDK1.4.2-b22)
      JCK : JCK1.4a-runtime
      Platform[s] : all
      switch/Mode : default
      JCK test owner : http://javaweb.eng/jck/usr/owners.jto
      Falling test[s]: api/java_lang/StringBuffer/serial/index.html#ConstructorTests
                        [ConstructorTest0001, ConstructorTest0002, ConstructorTest0003, ConstructorTest0004, ConstructorTest0005]

      JCK1.4a-runtime api/java_lang/StringBuffer/serial/index.html#ConstructorTests test fails with
      JDK1.5.0-b05 on all platforms.

      The test supposes that java.lang.StringBuffer class has "shared" field,
      but Specification does not require it.

      The test uses javasoft.sqe.serial.StreamObjectClass.StreamBuffer class to check java.lang.StringBuffer
      object structure. Here is source code fragment:

      --------- src/share/classes/javasoft/sqe/serial/spec/java/lang/StringBuffer.java ---------
      ...
      046> /* This method defines all the serializable fields */
      047> public void define() {
      048> if (ver >= 1.1) {
      049> defineField("count", INT);
      050> defineField("shared", BOOLEAN);
      051> defineField("value", CHARARRAY);
      052> }
      ...
      ------------------------------------------------------------------------------------------

      Java.lang.StringBuffer class contains "protected boolean shared" field in previous JDK builds,
      that is why the test passes with previous JDKs.

      Test source location:
      =====================
      /java/re/jck/1.4a/archive/fcs/binaries/JCK-runtime-14a/tests/api/java_lang/StringBuffer/serial/Version.java

      jtr file location:
      ==================
      /net/jtgb4u4c.sfbay/export/sail15/results/tiger/b05/jck14a/win32/win2000_smp_plugin_ie6.0_linux-22/workDir/api/java_lang/StringBuffer/serial/index_ConstructorTests.jtr

      How to reproduce:
      =================
      Run the following script (you may need to change it's JDK and JCK variables):
      --- script start ---
      #!/bin/bash
      JCK="/java/re/jck/1.4a/archive/fcs/binaries/JCK-runtime-14a"
      JDK="/java/re/jdk/1.5.0/promoted/latest/binaries/linux-i586"
      export CLASSPATH="$JCK/classes:$JCK/lib/javatest.jar"
      $JDK/bin/java javasoft.sqe.tests.api.java.lang.StringBuffer.serial.ConstructorTests
      --- script end ---
