---------------------------------------
Summary: [BeanUtils2] Handling of InstantiationException in
DefaultClassAccessor.newInstance() should be improved to give users better
feedback
Key: SANDBOX-441
URL: https://issues.apache.org/jira/browse/SANDBOX-441
Project: Commons Sandbox
Issue Type: Improvement
Components: BeanUtils2
Affects Versions: Nightly Builds
Reporter: Benedikt Ritter
Priority: Minor
Fix For: Nightly Builds
The handling of InstantiationException could be improved to give users a better
feedback of what went wrong (see JavaDoc of Class<T>.newInstance() for reasons
why instantiation may fail):
* check if a default constructor is available and throw
NoSuchConstructorException if not
* else throw BeanInstantiationException but inspect beanType in
BeanInstantiationException and set specific messages for the following cases:
** BeanType is abstract
** BeanType is an interface
** BeanType is a primitive type
** BeanType is an array type
** BeanType represents void
** if none of the above use a generic message
