      Proposed workaround
      ==================

      8) I managed to fix the situation temporarily as follows (but I am not
      convinced this is the correct way to comprehensively tackle the problem)
          Edit C:\solr-7.4.0\bin\solr.cmd as follows:
          Change all occurrences of '-Dlog4j.configurationFile="file:' to
      '-Dlog4j.configurationFile="' (19 occurrences in total)
          Change all occurrences of 'LOG4J_CONFIG=file:*' to '*LOG4J_CONFIG=' (2
      occurrences in total)

      9) Execute the following command: solr.cmd restart -p 8983

      10) The following console output appears:

      c:\solr-7.4.0\bin>solr.cmd restart -p 8983 
      Stopping Solr process 20024 running on port 8983 
      
      Gewartet wird 0 Sekunden. Weiter mit beliebiger Taste...
