------------------------------------------

             Summary: Regex testcase filtering: exception when hashmark is 
regex-quoted
                 Key: SUREFIRE-1250
                 URL: https://issues.apache.org/jira/browse/SUREFIRE-1250
             Project: Maven Surefire
          Issue Type: Bug
          Components: Maven Surefire Plugin
    Affects Versions: 2.19.1
            Reporter: Zoltan Haindrich
            Priority: Minor


i've been using regex to select which tests to run...and i've got some wierd 
exceptions when executing

{{code}}
mvn test "-Dtest=%regex[.*\Q#\E.*]"
{{code}}

executing the above command results in:

{{code}}
java.util.regex.PatternSyntaxException: 
Illegal/unsupported escape sequence near index 1
\E.*

{{code}}

i noticed earlier that maven might do some black-magic with these regexps in 
the background ( i know that it should know the class name earlier; to avoid 
starting testcases which will get entirely excluded...and thats cool )

...so..i assume maven does split the regex by the {{#}}; and that's okay - if 
that can't be avoided; place some pointers in the documentation about it and/or 
a more descriptive exception could be useful
