Bug fix to ensure that turning off Java Features applies to appropriate matlab versisions:

i.e., 7.0-7.4 as intended, rather than versions greater than 7, which would also include version 8. 

this line
if ( (mVersion >= 7) && (mMinorVersion < 4)) % version 7, < 7.4

was changed to
if ( (mVersion == 7) && (mMinorVersion < 4)) % version 7, < 7.4

Hopefully we can soon eliminate all code pertaining to java features in vistasoft.
