The code inside JspAnalyzerPlugin to detect if the taglib is provided locally in the module uses a different root than the one the JSP compiler uses. So it seems impossible to have both systems to find the taglib which results in either a compile failure or a Require-Capability generation, which forces to export the tag library to be imported by the module itself.
