* @summary converted from VM Testbase nsk/jdb/step/step002.
* VM Testbase keywords: [jpda, jdb]
* VM Testbase readme:
* DECSRIPTION
* The test for the 'step' command.
* The test checks the following cases:
* - step inside current method,
* - step into called method,
* - step up to calling method.
* The test works as follows. The jdb sets breakpoint at the line
* where new value is assigned to local variable. The jdb issues
* 'step' command. Then the test checks whether a step is done by
* requesting a value of local variable using 'eval' command.
* The next two cases are checked with a pair of 'step' and
* 'where' commands. The test checks a stack trace after step
* using 'where' command.
* The test consists of two program:
* step002.java - test driver, i.e. launches jdb and debuggee,
* writes commands to jdb, reads the jdb output,
* step002a.java - the debugged application.
* COMMENTS
* This test replaces the nsk/jdb/step/step002 one.
*
* @library /vmTestbase
