RFR: JDK-8208473: [TESTBUG] nsk/jdb/exclude/exclude001/exclude001.java is timing out on solaris-sparc again

[Gary Adams]

The test failure has been identified due to the "int[2]"
being misrecognized as a compound prompt.  This caused a cont
command to be sent prematurely.

The proposed fix waits for the correct prompt before
advancing to the next command.
