------------------------------------------------------------------------------
The following code will reproduce the issue. It seems this is triggered when a
defaultValue of null is used:
import java.util.Locale;
import org.apache.commons.beanutils.Converter;
import org.apache.commons.beanutils.locale.converters.IntegerLocaleConverter;
public class Test {
public static void main(String[] args) {
Converter converter = new IntegerLocaleConverter(null,
Locale.US);
// THIS WILL ALSO FAIL IF "null" IS PASSED,
// INSTEAD OF AN EMPTY STRING
Integer result = converter.convert(Integer.class, "");
System.out.println(result);
}
}
Result:
Exception in thread "main" org.apache.commons.beanutils.ConversionException:
Unsupported target type: class java.lang.Integer

org.apache.commons.beanutils.locale.BaseLocaleConverter.checkConversionResult(BaseLocaleConverter.java:287)
