You might want to wait until the patch for DERBY-104 is committed before making 
this change.  That patch was posted by Bernt Johnsen yesterday morning and I 
just reviewed it today.  It has yet to be committed.

Based on the patch proposed by Bernt Johnsen, the length of an index name _is_ 
going to change to 128, while the max length of a floating point constant is 
going to remain at 30.  The max length of an index name is already in the table 
you mentioned (second row from the bottom, it's given as 18, which will need to 
change).  Since the table header is "identifier length" and all of the entries 
refer to "names", I would think that the floating point limit should not be 
included in that table--that's a limit on the literal value itself, not on the 
name of any particular database identifier.
