Accept hexadecimal values in rule LHS

It is not possible to use a hexadecimal value in the LHS of a rule.

The manual says: "All standard Java numeric primitives are supported." As hexadecimal values are standard Java numeric primitives, this could be considered not just a new feature, but a bug (documentation bug at least).

I found this issue first mentioned in the referenced user forum post from 2006; sadly, the poster did not create a JIRA issue as suggested, or at least I could not find one.

Example:

rule "bla"
when
Value( tag == 0x00080060 ) // ERROR!
then
//something
end
