/*
 * @test
 *
 * @bug 4689395
 * @summary converted from VM Testbase nsk/jdb/regression/b4689395.
 * VM Testbase keywords: [jpda, jdb]
 * VM Testbase readme:
 * DESCRIPTION
 *     Regression test for the bug
 *         4689395 (P4/S3) "step over" after a class is redefined acts like "step out"
 *         Release summary: 1.4
 *         Hardware version: generic
 *         O/S version (unbundled products): 5.8
 *     The test consists of two java-files:
 *         b4689395.java  - launches jdb and debuggee, writes commands to jdb,
 *                          reads the jdb output;
 *         b4689395a.java - the debugged application.
 *     The debugged application (b4689395a.java) defines method minor() that
 *     prints four lines into System.out. b4689395 sets a breakpoint on the 54th
 *     line
 *         System.out.println("A breakpoint is here.");
 *     and then redefines b4689395a with newclass/b4689395a. Those classes differ
 *     just in the 30th line (period is omitted in newclass/b4689395a). After that
 *     the debuggee invokes 'next' command. The test fails if
 *     b4689395.ERROR_MESSAGE message appears in output, otherwise the test passes.
 * COMMENTS
 *     The test reproduces the bug on Solsparc.
