Description

Searching nodes for a group which got a criteria based on a wrong regexp will timeout with the message "Server cannot be contacted".
I met the case by using a criteria: Node Summary => Hostname => Regexp => debian-7-[0-9](2).* (using parenthesis instead of curled brace) for example.

I think this may be the same as #3734, but I'm not sure. Let's wait until it's fixed, then check again.

It could be linked to #3674, as suggest: http://www.rudder-project.org/redmine/issues/3674#note-36.

Nicolas, do you think it could be the case?

It seems to be related. Actually, I can't reproduce the issue but Nicolas and me are convinced that it was related to PostgreSQL.

I suppose we can reject this bug.

I'm resurecting the bug
Using a really invalid regexp (like debian-7-[0-9)(2). ) causes the applicatin to fail

The logs contain
java.util.regex.PatternSyntaxException: Unclosed character class near index 17
debian-7-[0-9)(2).
                 ^

Apply on 2.4 (without the dreaded Server Cannot Be Contacted at this time) up to 2.7
