EL evaluates null Number expression as zero
Issue
Null EL expression (e.g. #{nullNumber}) is evaluated as zero instead of null when it is assigned to non-primitive Number type.
The system property org.apache.el.parser.COERCE_TO_ZERO has no effect.
Environment
- JBoss EAP 6
- Expression Language (EL) 2.1 / 2.2
