 * @test
 *
 * @summary converted from VM Testbase nsk/jdb/where/where005.
 * VM Testbase keywords: [jpda, jdb]
 * VM Testbase readme:
 * DECSRIPTION
 *  A test case for the 'where' command. The debugged 'where005a'
 *  application throws a null pointer exception in 'func6()' method.
 *  The test passes if the 'where' command produces the correct
 *  stack trace.
 * COMMENTS
 *  This test functionally equals to nsk/jdb/where/where002 test
 *  and replaces it.
 *  Modified due to fix of the bug:
 *  4818762 TEST_BUG: two jdb test incorrectly check debuggee exit code
 *
 * @library /vmTestbase
 *          /test/lib
