    TROUBLESHOOTING AND BACKGROUND INFO NEEDED IN ORDER TO
    UNDERSTAND THE ISSUE:
    
    Note: The issue can not be reproduced by IBM in Citrix
    Environment or
    N/D Roaming as tested by Citrix Team and Roaming PAE.
    
    Citrix PAE pointed out that the issue is not being caused by
    Citrix but
    may be caused by the Eclipse windows save state function.
    
    Customer tested the workaround to disable save state and indeed
    then no
    error occurs in their environment.
    
    Customer feedback:
    
    >>>
    The workaround (disabling "save state") is not a perm fixture as
    this
    will affect a policy setting we have set by default, if we ask
    users to
    apply this in all cases it effectively takes away some nice
    functionality.
    <<<
    
    Feedback from XPD PAE:
    
    >>>
    In My previous update I explained this might be caused because
    of the
    workspace folder in the Notes Data directory is recreated at
    each launch
    due to their whole data directory being copied from another
    location.
    
    When customer disables
    Eclipse has preferences stored for that OS and I think they will
    see
    this error when ever the workspace folder is moved from one
    machine to
    another. I am not aware of a fix as this is not a supported
    configuration.
    
    They should be using Domino Roaming instead and not roam the
    whole data
    directory.
    
    If the customer and AVL wants an official answer, please
    escalate to L3
    for review and their comments.
    <<<
    
    AVL went onsite and provided the following infos:
    
    Notes Standard (Eclipse) Client 8.5.1 + FP4 uses either Citrix
    or AAM's
    own Roaming User, both of which use Panagenda file re-direction
    to
    selectively save and restoring Notes Data + some Eclipse files
    to save
    server disk space.
    
    Domino uses both SMTP based Routing combined with Fully
    Distinguished
    Names routing.
    
    These are all deemed Critical Production systems all recently
    upgraded
    to 6.x => 8.5.1 and very recently upgraded to FP4 to fix DAOS
    issues.
    
    AAM uses Notes Standard (Eclipse) Client 8.5.1 + FP4 either over
    Citrix
    or using AAM's own Roaming User, both of which use
    Panagenda file re-direction to selectively save and restoring
    Notes
    Data + some Eclipse files to save server disk space.
    
    The Panagenda product instantly backs-up selected files (*.xml
    *.prefs
    *.dic ) on each exit from Notes and then instantly restores them
    as
    Notes is started.
    
    Unfortunately they appear to have forgotten to add in at least
    one key
    file (perspectivemap.properties) that appears to store the Notes
    state
    changes under Eclipse:

    This particular file clearly stores the names and positions of
    the open
    tabs and current views, such that when the option to Restore All
    Settings on Startup is enabled, this file is updated (as above)
    but
    since it isn't backed up, they don't get the correct State
    restored
    (they never did, but didn't actually realise this has never
    worked!)
    and this Eclipse file omission from Panagenda backup also seems
    to
    causes Eclipse to issue a Windows Java error on startup if "Save
    State
    on Shutdown" is enabled:
    
    Message:
    
    >>>
    "Registry event dispatcher" has encountered a problem.
    
    Error notifying registry change listener.

       Error notifying registry change listener.
       Invalid thread access
    <<<
    
    Please find Screenhots, Notes error logs and nsd attached to the
    SPR.
    
    This error suggests that Eclipse is attempting to over-ride or
    ignore
    the fact that an expected file has invalid content or is
    missing, but
    is denied the ability to change something in the registry. I am
    speculating at what the error actually means.
    
    The file perspectivemap.properties is updated when Notes is shut
    down,
    but then not "used" during the startup!!
    
    We played with this file for a while, and if the file contents
    are
    manually changed, eg we editted a tab and view out of it, it
    didn't
    change the startup (ie it ignore our edit), suggesting that
    after
    writing the contents to perspectivemap.properties on Notes
    shutdown,
    Eclipse subsequently placed the contents of the file "somewhere
    else",
    (in the Registry, possibly?) and then read the contents from
    that
    location, not the text file we had just editted, when it
    restarted.
    
    We had disabled Panagenda during this testing, to stop it
    overwriting
    our editted file on restart, as it possibly might have.
    
    Although we don't backup or recover this file with Panagenda, it
    will
    be recovered from the generic "zip" of all the Eclipse files
    that
    Panagenda  loads initially , then Panagenda loads the users own
    unique
    saved files (*.xml *.prefs *.dic ) which are over-laid on top of
    the
    standard generic "zipped up" set, then finally Notes is allowed
    to
    start up.
