/*
 * @test
 * @bug 4373996
 * @summary parser incorrectly ignores a principal if the principal name
 *      expands to nothing.
 * @run main/manual PrincipalExpansionError
 */

/*
 * This test is a bit complicated.
 * 1) PrincipalExpansionError.java
 *         the test itself.  this test creates a Subject with a
 *         UnixPrincipal("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 UnixPrincipal("TestPrincipal")
 *                 was also granted the file permission,
 *                 but it has a bogus second UnixPrincipal 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 UnixPrincipal("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
