            Bug ID: 137206
           Summary: LibreOffice 7.0 - Binary URP bridge already disposed
           Product: LibreOffice
           Version: 7.0.1.2 release
          Hardware: All
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: sdk
          Assignee: libreoffice-bugs at lists.freedesktop.org

Description:
Hello,

we use LibreOffice CALC to automatically generate ODS files in a web
application running in IIS (Windows Server 2016 in a VM) For this purpose we
use the LibreOffice SDK and the CLI component. The component addresses the
LibreOffice CALC application installed on the server side.
Since version 7.0, we get the error "Binary URP bridge already disposed" if we
repeatedly address LibreOffice. But this error occurs only up from the second
call.

With LibreOffice 6.4.6, this error did not occur. Furthermore, the error does
not occur in version 7.0 if the web application is not running in IIS but in
the VisualStudio development environment (with IIS Express). 

We suspect a bug in LibreOffice 7.0 here.

We have identified the following manual workaround:
- Starting LibreOffice CALC on the server
- Now the web application generates an ODS file via the CLI component 
- While the web application creates the ODS file (here our web application
shows a permanent waiting bar), the previously started CALC instance on the
server is terminated 
- The creation of the ODS file is now successfully continued
- For future calls the error will no longer occur

If the workaround is not executed, the above error message is displayed after a
few seconds up from the second call.

Many greetings,
Marc
