I think the problem is that floating point literals must be written
in base 10, unlike integer literals which can be written in octal.
In your case:

   00.1.class

the parser sees "00" as as 0 written as an octal constant.  The parser
doesn't consider it as the start of a floating point value because
floating point values must be written in decimal.  So after parsing
the "00" as an integer literal it sees ".1" as a no longer supported
floating point literal and complains.
