Summary: ELSupport.coerceToNumber with Number as type
Product: Tomcat 6
Version: 6.0.18
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: normal
Priority: P2
Component: Jasper

I have recently upgraded to 6.0.18 and i am getting this exception:
java.lang.IllegalArgumentException: Cannot convert 0 of type class
java.lang.Long to class java.lang.Number
at org.apache.el.lang.ELSupport.coerceToNumber(ELSupport.java:252)

I have got a function, which can format any Number to String.
<function-signature>java.lang.String
formatNumber(int,java.lang.String,java.lang.String,java.lang.Number)</function-signature>
But it seems coerceToNumber can't handle a Number as Type.
Possible Solution:
If ELSupport.coerceToNumber is called with any Number instance as the first
Parameter ('number')and Number.class as second ('type') it should return the
first parameter without conversion.
