    After installing PM81406 (or applying fix packs 8.0.0.6,
    8.0.0.7, 8.0.08 or 8.5.5.1) the following exception can occur
    during JSP compilation:
    /testApp/_HelloWorld.java : 3476 : Invalid
    escape sequence (valid ones are \b \t \n \f \r \" \' \\ )
    This will only occur if a custom tag is written to allow for
    dynamic attributes and the value of that attributes contains
    backslashes.
    An example:
    <PI10294:MyTag dynAttr="\\w\\d" />
