[hibernate-issues] [Hibernate-JIRA] Created: (HV-445) Ensure meta models are completely unmodifiable

Ensure meta models are completely unmodifiable ---------------------------------------------- Key: HV-445 URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-445 Project: Hibernate Validator Issue Type: Improvement Reporter: Gunnar Morling Fix For: 4.2.0.CR1 The internal meta model (BeanMetaDataImpl et al.) as well as the external one (BeanDescriptorImpl et al.) should be completely unmodifiable, as they could potentially be accessed from multiple threads at the same time. I made some more fields final/unmodifiable with HV-371, but there are some places left which I couldn't change easily and need some more consideration: * ConstraintDescriptorImpl#compositionType * ElementDescriptorImpl#constraintDescriptors * BeanMetaDatImpl#cascadedMembers (could be made unmodifiable after initialization instead of creating a new unmodifiable set with each call of getCascadedMembers() When looking through the model I found it quite complex to find out which collection fields are already unmodifiable and which not. I therefore thought about introducing a marker annotation @Unmodifiable which could be used to document unmodifiable fields.
