Spaces crashes after deploying a custom task flow as shared library and extending Spaces with it.
The exception is the following:

Error is: 'weblogic.application.ModuleException: Failed to load webapp: '/wcsdocs''
weblogic.application.ModuleException: Failed to load webapp: '/wcsdocs'
at weblogic.servlet.internal.WebAppModule.prepare(
Caused By: Error: Unresolved Webapp Library references for "ServletContext@2354986[app:webcenter module:/wcsdocs path:/wcsdocs spec-version:2.5 version:]", defined in weblogic.xml [Extension-Name: libtaskflow, exact-match: false]
at weblogic.servlet.internal.WebAppServletContext.processWebAppLibraries(



Steps to reproduce:

1.  Create a simple project with a taskflow.
2.  Deploy it as a shared library (named libtaskflow) in Weblogic Server.
3.  Add the reference to this library in DesignWebCenterSpaces project weblogic.xml, as documented at:
    49 Extending WebCenter Spaces Using JDeveloper of Oracle Fusion Middleware Developer's Guide for Oracle WebCenter11g Release 1 (11.1.1)

4. Use the "ant" file in DesignWebCenterSpaces to deploy the custom extend.spaces.webapp library.
    The custom extend.spaces.webapp needs to be undeployed and Spaces need to be restarted to get it running again.
