 * @summary converted from VM Testbase nsk/jdb/caught_exception/caught_exception002.
 * VM Testbase keywords: [jpda, jdb]
 * VM Testbase readme:
 * DECSRIPTION
 *  A positive test case for the 'catch caught <exception>' command.
 *  When the debugee throws an exception that is caught somewhere
 *  up in the program stack, jdb does not halt execution at the point
 *  the exception was thrown but continues to execute the code in the catch
 *  clause and proceed on with the rest of the program.
 *  To halt execution at the throw point for exceptions
 *  that are being caught - the 'catch' command has to be used.
 *  The test throws ten exceptions that are on jdb's catch list
 *  and verifies that jdb halts execution at the throw point each
 *  time an exception is thrown.
 * COMMENTS
 *  This test functionally equals to
 *  nsk/jdb/caught_exception/caught_exception001 test and replaces it.
 *
