--------------------------------------------
Summary: Warnings from FluentPropertyBeanIntrospector when
creating a CombinedConfiguration from a CombinedConfigurationBuilder
Key: CONFIGURATION-603
URL: https://issues.apache.org/jira/browse/CONFIGURATION-603
Project: Commons Configuration
Issue Type: Bug
Affects Versions: 2.0
Environment: Windows 7 x64, Java 1.7, Apache Commons Configuration
2.0-alpha2
Reporter: Richard Tearle
When creating a CombinedConfiguration from a CombinedConfigurationBuilder we
get a number of warnings from FluentPropertyBeanIntrospector whilst it's trying
to get PropertyDescriptors for the following methods:
AbstractConfiguration.setProperty and MultiWrapDynaBean.set.
Is there a way to suppress these warnings or some other fix, as our testers
keep reporting the warnings as errors.
The following is a simple example of the code that should reproduce this issue:
{code}
@Test
public void configurationTestExample() {
List<FileLocationStrategy> subs = Arrays.asList(
new ProvidedURLLocationStrategy(),
new FileSystemLocationStrategy(),
new ClasspathLocationStrategy());
FileLocationStrategy strategy = new CombinedLocationStrategy(subs);
Parameters params = new Parameters();
CombinedConfigurationBuilder builder = new
CombinedConfigurationBuilder()
.configure(
params.fileBased()
.setFile(new File("Configuration.unitTest.xml"))
.setLocationStrategy(strategy)
.setListDelimiterHandler(new
DefaultListDelimiterHandler(';'))
);
try {
CombinedConfiguration config = builder.getConfiguration();
config.hashCode();
} catch (org.apache.commons.configuration2.ex.ConfigurationException e)
{
e.printStackTrace();
}
assertTrue(true);
}
{code}
and here is the stack trace
{code}
