             Summary: Data Race in StringEscapeUtils.escapeXml
                 Key: LANG-1170
                 URL: https://issues.apache.org/jira/browse/LANG-1170
             Project: Commons Lang
          Issue Type: Bug
          Components: lang.*
    Affects Versions: 2.6
         Environment: Windows JDK 1.8
            Reporter: Thomas Krieger
            Priority: Minor


Calling StringEscapeUtils.escapeXml from many threads creates a data race in 
the methods:

  private String[] lookupTable() {
            if (lookupTable == null) {
                createLookupTable();
            }
            return lookupTable;
        }
