Oliver Heger commented on BEANUTILS-477:
----------------------------------------
Ticket was moved to BeanUtils.
The only work-around I currently see is indeed to change the logging
configuration so that these logs are suppressed.
> Warnings from FluentPropertyBeanIntrospector when creating a
> CombinedConfiguration from a CombinedConfigurationBuilder
> ----------------------------------------------------------------------------------------------------------------------
>
> Key: BEANUTILS-477
> URL: https://issues.apache.org/jira/browse/BEANUTILS-477
> Project: Commons BeanUtils
> Issue Type: Bug
> Affects Versions: 1.9.2
> Environment: Windows 7 x64, Java 1.7, Apache Commons Configuration
> 2.0-alpha2
> Reporter: Richard Tearle
> Labels: newbie
>
> 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}
