--- Comment #1 from Mark Thomas <ma...@apache.org> ---
From the EL 2.2 specification:

Identifier ::= Java language identifier

float is not a valid Java identifier because it is a reserved word in Java.

The same constraint was present in the EL 2.1 specification but Tomcat 6 was
not as strict.

In 7.0.x onwards you can disable this additional check using:
-Dorg.apache.el.parser.SKIP_IDENTIFIER_CHECK=false

although the right thing to do would be to fix the app.
