SPEL: NullPointerException when passing null values as parameters to method calls [SPR-5661]

[spring-projects-issues]

Oliver Becker opened SPR-5661 and commented

Currently it is not possible to pass a null value as a parameter to a method in SPEL, because Spring tries to determine the class of the passed parameter, which results in a NullPointerException:

java.lang.NullPointerException
at org.springframework.expression.spel.ast.MethodReference.getTypes(MethodReference.java:94)
at org.springframework.expression.spel.ast.MethodReference.getValueInternal(MethodReference.java:76)
at org.springframework.expression.spel.ast.CompoundExpression.getValueInternal(CompoundExpression.java:53)
at org.springframework.expression.spel.ast.Ternary.getValueInternal(Ternary.java:52)
at org.springframework.expression.spel.ast.SpelNodeImpl.getValue(SpelNodeImpl.java:51)
at org.springframework.expression.spel.SpelExpression.getValue(SpelExpression.java:64)

Of course Spring should be able to handle such values.

I happened to have fixed this last night in the repo. Regression test added.
