[jsr-314-open-mirror] [jsr-314-open] Coercion in the EL

[Kito Mann]

I just ran into this while upgrading an application from MyFaces 1.1 to
Mojarra 1.2. In MyFaces 1.1, empty strings were converted to null for Long
properties in a backing bean. Now, they are converted to 0. I found several
postings about this issue, culminating in this bug:
https://jsp-spec-public.dev.java.net/issues/show_bug.cgi?id=183.

So, unless I'm missing something, this issue is really the same as
https://uel.dev.java.net/issues/show_bug.cgi?id=12. If everyone agrees, I'll
go ahead and update the description accordingly, since the description
currently mentions Booleans only, not number values.

Are there any plans to address this issue in 1.2 branches of the
implementations?
