MappedPropertyDescriptor throws an exception after method reference has been
garbage collected
----------------------------------------------------------------------------------------------
Key: BEANUTILS-347
URL: https://issues.apache.org/jira/browse/BEANUTILS-347
Project: Commons BeanUtils
Issue Type: Bug
Components: Bean / Property Utils
Affects Versions: 1.8.0
Reporter: Eickvonder
If a bean contains a method
setAnyMapped(anyTypeButString,anyType)
without a corresponding getter the first calls to getMappedWriteMethod return
the corresponding method, but if the soft reference to the method has been
garbage collected the runtime exception 'Method ... for ... could not be
reconstructed - method not found" is thrown.
First of all I think it is a bug that getMappedWriteMethod is not invariant in
its behaviour concerning garbage collection (at least it should not throw an
exception in this case), but secondly I wonder if it is correct at all that
constructing a MappedPropertyDescriptor is possible though the first parameter
is not of type String. But this "odd" behaviour is actually tested within
MappedPropertyTestCase.testAnyArgsProperty().
For me I would be fine if either construction of MappedPropertyDescriptor would
fail or getMappedWriteMethod would return null or the method in both cases
before and after garbage collection. The only thing that breaks my app is the
exception being thrown as this is not catched within my call of
BeanUtils.populate.
