Using '"*"' in bash causes a "*" (i.e., double-quote, asterisk,
double-quote) to be passed to a program.  I just verified this with an
"echoargs" program compiled with both mingw and MSVC.  When I use a
'"*"' on the command line the mingw or msvc application sees a "*" as
its argv[0].

Or, more specifically, what the programs sees is:

c:\tmp\echoargs.exe "\"*\""

It looks like java is somehow confused by this.  I really don't
understand why it should but it still looks like a problem with the java
program to me.
