Roman Puchkovskiy updated JCR-1597:

Attaching proposed patch. This just uses ResourceException(String, Throwable) constructor.
Not sure, is this correct, please review.

>             Project: Jackrabbit
>          Issue Type: Bug

> 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().
