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.
Issue: SPR-11064
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.
Issue: SPR-10657
Use LinkedHashMaps/Sets wherever exposed to users, and code tests defensively in terms of expected Map/Set ordering. Otherwise, there'll be runtime order differences between JDK 7 and JDK 8 due to internal HashMap/Set implementation differences.
Issue: SPR-9639
Provide an additional constructor on SpelParserConfiguration that can
be used to limit the maximum size that a collection will auto grow when
being accessed via a SpEL expression.
This constraint is particularly useful when SpEL is used with data
binding as it prevents a malicious user from crafting a request that
causes OutOfMemory exceptions.
Issue: SPR-10229
Update ReflectivePropertyAccessor to search for fields on super classes
and implemented interfaces.
Although the javadoc Class.getFields() implies that all public fields
of class should be returned SpelReproTests demonstrates that this is
not always the case.
Issue: SPR-10125
Fix SpEL expression parser and tokenizer to provide better exceptions
when dealing with operations that expect two operands. For example,
prior to this commit the expression '/foo' would throw a NPE due
to missing operands to the left of '/'.
