This is somewhat fragile area of the launcher code. I don't think the 
processing of --class-path should set the mode as the class path can be 
used in conjunction with other options. The -jar and -m option will 
select the mode of course but other cases should probably leave it as 
LM_UNKNOWN until the final determination with IsSourceFile.
