JCARepositoryHandle.login(...) methods never throw NoSuchWorkspaceException
---------------------------------------------------------------------------

                 Key: JCR-1597
                 URL: https://issues.apache.org/jira/browse/JCR-1597
             Project: Jackrabbit
          Issue Type: Bug
          Components: jackrabbit-jca
    Affects Versions: 1.4
            Reporter: Roman Puchkovskiy


Call sequence:
  JCARepositoryHandle.login(Credentials, String)      // (here non-existent 
workspace is specified for login)
    JCARepositoryHandle.login(JCAConnectionRequestInfo)
      ConnectionManager.allocateConnection(ManagedConnectionFactory, 
ConnectionRequestInfo)
        ...
          JCAManagedConnection.openSession(JCAConnectionRequestInfo)
            Repository.login(Credentials, String)        // here 
NoSuchWorkspaceException is thrown, catched by 
JCAManagedConnection.openSession(JCAConnectionRequestInfo), _set as 
linkedException_ to ResourceException, which is thrown
        ...
     Here (in JCARepositoryHandle.login(JCAConnectionRequestInfo)) 
ResourceException is caught, its _cause_ is retreived, and, if cause is 
NoSuchWorkspaceException, it's thrown, else another exception is thrown.

Note, that when exception occures on lower level, it's wrapped in 
ResourceException using setLinkedException(), but on upper level it's unwrapped 
using getCause(). But cause is not set by anyone, it's null, so 
NoSuchWorkspaceException is never thrown here.

Suggested fix is to use same mechanism on both ends: either change wrapping 
mechanism to exception chaining (new ResourceException(msg, cause)), or unwrap 
using ResourceException.getLinkedException().
