 * @test
 * @bug 4373996
 * @summary parser incorrectly ignores a principal if the principal name
 *      expands to nothing.  this test is a bit complicated.
 *
 *      1) PrincipalExpansionError.java
 *              the test itself.  this test creates a Subject with a
 *              SolarisPrincipal("TestPrincipal") and calls doAs
 *              with a PrincipalExpansionErrorAction.
 *
 *      2) PrincipalExpansionErrorAction
 *              this action tries to read the file, /testfile
 *
 *      3) to run the test:
 *              a) jtreg -verbose:all -testjdk:<your_jdk>/build/sparc
 *                      PrincipalExpansionError.java
 *              b) PrincipalExpansionError is compiled and put into
 *                      the "test.classes" directory
 *              c) PrincipalExpansionErrorAction is compiled and put into
 *                      the "test.classes"/apackage directory
 *                      (since it belongs to the 'apackage' package
 *              d) the PrincipalExpansionError shell script moves
 *                      test.classes/apackage to test.src/apackage.
 *                      this guarantees that the test will run
 *                      with codebase test.classes, and the action
 *                      will run with codebase test.src.
 *              e) the test is executed.  permissions to read the file,
 *                      /testfile, were granted to the PrincipalExpansionError.
 *                      the policy entry for PrincipalExpansionErrorAction
 *                      running as SolarisPrincipal("TestPrincipal")
 *                      was also granted the file permission,
 *                      but it has a bogus second SolarisPrincipal with
 *                      a name that can't be property-expanded.
 *
 *                      the old behavior of the code would ignore the
 *                      bogus entry and incorrectly grants the file permission
 *                      to SolarisPrincipal("TestPrincipal").
 *                      the new behavior correctly ignores the entire
 *                      policy entry.
 *                      Please note that the jtreg needs to be granted
 *                      allpermissions for this test to succeed. If the codebase
 *                      for jtreg changes, the PrincipalExpansionError.policy
 *                      needs to be updated.
 *
 *              f) original @ tags:
 *                      compile PrincipalExpansionErrorAction.java
 *                      run shell PrincipalExpansionError.sh
 *                      run main/othervm/policy=PrincipalExpansionError.policy
 *                              -Djava.security.debug=access,domain,failure
 *                              PrincipalExpansionError
 *
 * @ignore unable to rely on location or javatest.jar
 *              (so we can grant it AllPermission)
