      Description

          try {
      
          } catch (Unknown1| Unknown2 e) {
            // e.symbolType() is Object, incorrect
          } catch (Unknown1| IllegalArgumentException e) {
            // e.symbolType() is Object, incorrect
          } catch (IOException| IllegalArgumentException e) {
            // e.symbolType() is Exception, correct
          }
      
      

      This typically happens when the project is not configured correctly (probably sonar.java.libraries missing).
      This introduces FP in S3457 (only when the semantic is incomplete).
