Inconsistent results when using SpEL's OpLE and OpGE to handle null values #33981
Closed as not planned
Description
SpEL expression 1: #T_34900>=0.0
SpEL expression 2: #T_34900<=0.0
When #T_34900 value is NULL:
- Expression 1 evaluates to
FALSE - Expression 2 evaluates to
TRUE
The reason is that StandardTypeComparator returns -1. Expression 1 is equal to -1 >= 0, and expression 2 is equal to -1 <= 0.
Is it a feature or a bug?
In my opinion, the compare result is stationary when input is NULL.
org.springframework.expression.spel.ast.OpLE line 65: return BooleanTypedValue.forValue(state.getTypeComparator().compare(left, right) <= 0);
org.springframework.expression.spel.ast.OpGE line 65: return BooleanTypedValue.forValue(state.getTypeComparator().compare(left, right) >= 0);
