    Description

      It is more useful and flexible to allow default value in the variable expression itself.
      For example, 

      ${var1:-defvalue1},
${ctx:request_id:-defvalue2}, etc.

      This generic feature has been included in StrSubstitutor of commons-lang3 as well with the following issue:

      The benefit from the feature with LANG-893 is we can use it more widely whenever used in look ups.
