      Description

      FULL PRODUCT VERSION :
      java version "9"

      A DESCRIPTION OF THE PROBLEM :
      Jshell crashes

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Enter jshell and import the java.lang.*
      Declare a StringBuilder (or StringBuffer)
      StringBuilder sb = new StringBuilder()
      Try to see the document by pressing tab multiple times for
      sb.append(
      will crash jshell. This is the stacktrace:

      <press tab again to see documentation>

      jshell> sb.append(Exception in thread "main" java.lang.StringIndexOutOfBoundsException: start -59, end -59, length 238

              at jdk.compiler/jdk.internal.shellsupport.doc.JavadocHelper$OnDemandJavadocHelper.getResolvedDocComment(JavadocHelper.java:481)

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Expected to see the java doc
      ACTUAL -
      jshell> import java.lang.*

      jshell> StringBuilder sb = new StringBuilder()
      sb ==>

      jshell> sb.
      append( appendCodePoint( delete( deleteCharAt( equals( getClass() hashCode() indexOf(
      insert( lastIndexOf( notify() notifyAll() replace( reverse() toString() wait(

      jshell> sb.append
      append( appendCodePoint(

      jshell> sb.append(
