Problem summary

  • ****************************************************************
    * USERS AFFECTED:  IBM WebSphere Application Server users of   *
    *                  JavaServer Pages (JSP)                      *
    ****************************************************************
    * PROBLEM DESCRIPTION: Expression Language (EL) expressions    *
    *                      might be escaped if used within a       *
    *                      large block of character data in a      *
    *                      JavaServer Pages (JSP) file.            *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When an EL expression is used within a large block of text,
    the expression might be escaped even though such expression
    did not have a preceding escape character ('\').
    

Problem conclusion

  • The JSP engine was modified to not escape EL expressions when
    they are within a character block and don't have a preceding
    escape character.
