-----------------------------------
Summary: camel-core - Bean binding: @PropertyInject hides an
invalid value, and overloaded constructors are not found
Key: CAMEL-25009
URL: https://issues.apache.org/jira/browse/CAMEL-25009
Project: Camel
Issue Type: Bug
Components: camel-core
Reporter: Claus Ibsen
A review of bean binding and dependency injection (CamelPostProcessorHelper,
PropertyBindingSupport) found the bugs below. Each one was reproduced against
4.23.0-SNAPSHOT.
# *@PropertyInject uses the default value when the property value is invalid.*
When the property existed but its value could not be converted to the type of
the field or parameter (such as port=80a for an int), the defaultValue was
silently used instead, so the mistake in the configuration went unnoticed. The
defaultValue is now only used when the property cannot be resolved (such as not
existing), and an invalid value fails.
# *A constructor or factory method overloaded for the given parameters is not
found.* When more than one constructor or factory method matched the
parameters, such as #class:java.math.BigDecimal(5) (constructors with int, long
and BigInteger), or a factory method overloaded with int and long, none was
chosen and the bean could not be created. The most specific is now chosen, as
Java would: a whole number is an int (and then a long), and a bean is of its
own type rather than a super type. When there is still no single most specific,
the previous behavior applies.
