I was adding last operators and found there is possibility to match "etarts_with" and "ntarts_with" as "starts_with" operator (there is no break at the and of case section and there is no condition for first character in case related to starts_with).
The same problem is with "eontains", "nontains" and "sontains" as "contains" operator.
And another one with "matches_*" operator with incorrect first letter (e,n,s,c).
JFrog no longer makes the build available bintray. Any chance you could make the jar available through GitHub releases or something like https://mvnrepository.com/repos/central?
Building from source is particularly difficult since it requires building the JTCL source, and that requires Sun jdk 1.6.
