Solution

Seems like your CLASSPATH is too long for Windows to cope with.

Google for "CreateProcess error=87, The parameter is incorrect". See also this answer.

You will need to shorten your classpath. Try to include only the actual dependencies of StockQuoteClient and nothing else, rather than all the "*.jar" entries.
