RFR [8014792] Need a test to check if path to java debugger has spaces

[Ivan Gerasimov]

Hello all!

Would you please help review a new regression test?
This is related to the fix for 8014676 (jdb could not run under Windows, 
if its path contained a space).

The test simply checks, if the path to the tested jdk contains a space 
and exits, if it does not.
Otherwise it tries to run the debugger. With the bug 8014676, the 
debugger will report IOExeption thrown.

The complicated part is that with the presence of no error, the debugger 
will not exit, but wait for the user command instead.
To prevent it, I pass a nonexistent option to the debuger. Thus it must 
fail with an error message.
