[jira] [Commented] (OAK-11486) Session-local namespace mappings for unregistered namespace URIs lead to unexpected ISE for Node.getName() or Node.getPath()

--------------------------------------

??If a JCR method is passed a name or path containing a prefix which does not exist in the local mapping an exception is thrown.??

I agree that this reads like every JCR method should throw an exception immediately if an unknown prefix is passed as a parameter. So this applies to multiple methods, because I think we are not doing this anywhere. Separate issue?

> When creating a node with an unknown prefix and afterwards mapping that prefix to an unregistered URI with {{Session.setNamespacePrefix(...)}} ([https://developer.adobe.com/experience-manager/reference-materials/spec/jsr170/javadocs/jcr-2.0/javax/jcr/Session.html#setNamespacePrefix(java.lang.String,%20java.lang.String]) calling its {{Node.getName()}} or {{Node.getPath()}} methods leads to an unexpected ISE.
> According to [https://developer.adobe.com/experience-manager/reference-materials/spec/jcr/2.0/3_Repository_Model.html#3.5.2%20Session-Local%20Mappings]
> bq. If a JCR method is passed a name or path containing a prefix which does not exist in the local mapping an exception is thrown.
> Therefore I would expect that adding a node with an unknown prefix leads to an exception immediately (without waiting for save()) while adding a node with a only local mapping should not throw an exception at all.
