Clean up compiler warnings in the tests of spring-expression. This
commit adds type parameters to some of the types (mostly `List` and
`Map`). Some of them can't be cleaned up, some tests are even
specifically for raw types.
Prior to this commit, the codebase was using a mix of log4j.xml
and log4j.properties for test-related logging configuration. This
can be an issue as log4j takes the xml variant first when looking
for a default bootstrap configuration.
In practice, some modules declaring the properties variant were
taking the xml variant configuration from another module.
The general structure of the configuration has also been
harmonized to provide a standard console output as well as an
easy way to enable trace logs for the current module.
When a node of an SPeL expression was a call to a bean referenced
in a method argument, the expression was resolved twice.
The resolved arguments are now specified to MethodValueRef instead
of resolving the arguments again in the constructor
Issue: SPR-11445
Fixed through falling back to the raw parameter type in the TypeDescriptor(MethodParameter) constructor, properly detecting the vararg array even in case of an unresolvable type variable, and through restoring getElementTypeDescriptor's original behavior for arrays, i.e. always returning a non-null descriptor.
Issue: SPR-11494
- Consistent importing of org.junit.Assert.*;
- Proper declaration of expected exceptions via @Test(expected).
- Renamed SpEL ExpressionTestCase to AbstractExpressionTests.
- Formatting and test method naming conventions.
Fix remaining Java compiler warnings, mainly around missing
generics or deprecated code.
Also add the `-Werror` compiler option to ensure that any future
warnings will fail the build.

Prior to this change, SpEL supported numeric operations for int, float,
ect. `new java.math.BigDecimal('0.1') > 0` evaluated to false
(BigDecimal is truncated to int)
This commit introduces support for BigDecimal operations for all
mathematical operators. `new java.math.BigDecimal('0.1') > 0` now
evaluates to true (the comparison is made with BigDecimals)
Issue: SPR-9164
Prior to this commit the SpEL operators `==` and `!=` were using the
Java `==` comparison operator as part of their equality checking. It is
more flexible to use the equals() method on Object.
Under this commit the change to .equals() has been made and the equality
checking code has been pushed into a common method in the Operator
superclass. This commit also makes some tweaks to the other operator
classes - the Float case was missing from OpGT.
Issue: SPR-9194
Update EvaluationException to expose the toDetailedString() method as
the exception message. The simple message can now be accessed via the
new getSimpleMessage() method.
Issue: SPR-10938
Update the `CacheKey` class used by `ReflectivePropertyAccessor` to
include if the target object is class. The prevents an incorrect cache
hit from being returned when a property with the same name is read on
both an object and its class. For example:
#{class.name}
#{name}
Issue: SPR-10486
Update getValue(EvaluationContext context, Object rootObject,
Class<T> desiredResultType) to propagate the EvaluationContext to
ExpressionUtils.
Issue: SPR-10953
Relax the method search algorithm used by `ReflectivePropertyAccessor`
to include methods of the form `getXY()` for properties of the form
`xy`.
Although the JavaBean specification indicates that a property `xy`
should use the accessors `getxY()` and `setxY()`, in practice many
developers choose to have an uppercase first character. The
`ReflectivePropertyAccessor` will now consider these style methods if
the traditional conventions fail to find a match.
Issue: SPR-10716
Update the cached MethodExecutor in MethodReference to include the
target type. Prevents the incorrect use of the cache when the
SpEL expression refers to a different target object.
Issue: SPR-10657
Update the cached MethodExecutor in MethodReference to include the
method argument types. Prevents the incorrect use of the cache when the
SpEL expression refers to a class that has overloaded methods.
