RFR: 8201544: Improve javac command line parsing and error reporting

[srinivas.dama at oracle.com]

Hi,

Please review http://cr.openjdk.java.net/~sdama/8201544/webrev.02/

for https://bugs.openjdk.java.net/browse/JDK-8201544.

This issue is specific to windows.

Currently when * character is present in filename passed through API 
call, javac throws weird exception message. With the fix, it is now 
modified to throw an error instead of exception.

Regards,

Srinivas
