      Description

      ADDITIONAL SYSTEM INFORMATION :
      openjdk version "1.8.0_232"
      OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_232-b09)
      OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.232-b09, mixed mode)

      A DESCRIPTION OF THE PROBLEM :
      This is an upstream bug for https://josm.openstreetmap.de/ticket/18862.
      The method javax.swing.text.html.FormView.appendBuffer will throw an NPE if value is null.
      This can happen when you submit an HTML form lacking a "select" option value.
      Only one of the three calls to this private method checks that value is not null, the two others can fail.

      Please add label "josm-found" to this bug report.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      1. Using a JEditorPane configured to render HTML, render https://josm.openstreetmap.de/ticket/18845
      2. Make sure the field "Version" is empty
      3. Enter some text at the bottom of the page and click "Preview" button

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      No error
      ACTUAL -
      java.lang.NullPointerException
