[Bug 63407] New: EL Compiler can not compile when the EL contains a
java reserved word
https://bz.apache.org/bugzilla/show_bug.cgi?id=63407
Bug ID: 63407
Summary: EL Compiler can not compile when the EL contains a
java reserved word
Product: Tomcat 7
Version: 7.0.94
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: Jasper
Assignee: dev@tomcat.apache.org
Reporter: pashazadeh@gmail.com
Target Milestone: ---
We have class in our project with a accessor method with signature of
public boolean isFloat() {}
when referencing this method in JSP ELs (having something like ${abean.float}),
JSP compiler throws an error during compilation of the JSP.
There was no such a problem in Tomcat 6.x but, Tomcat 7.x and Tomcat 8.5.x have
the same problem and can not compile the JSP when it contains float as a part
of EL path.
As a workaround I renamed the method to something else.

--- 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.
