Problems with FindBugs exclude filter

Regarding FindBugFilter,

(just to be sure) are you sure you are considering the compiled class files directories, and not the sourcePath? (as mentioned in this SO answer).

From the Java element name matching section:

If the name attribute of Class, Method or Field starts with the ~ character the rest of attribute content is interpreted as a Java regular expression that is matched against the names of the Java element in question.

Would the following regex be more accurate?

    <Class name="~.*\._.*"/>
    <Class name="~.*?EJS.*"/>

• ".*\._.*" instead of ".*\.^_*" because the anchor is supposed to match at the start of the string the regex pattern is applied to.

• ".*?EJS.*" instead of ".*EJS*" because the ? quantifier makes the matching lazy, avoiding to 'eat' EJS. (Plus "S*" means "0 or n S", which does not help here)
