Stepan, thanks for the patch, though there are some processes we'd like to use: 1. open a jira ( since HHH-766 is closed ) and link it to the original one (HHH-766) 2. give some numbers / tests to show your patch performs better than the old one 3. create a github pull request p.s. from what i found, org.hibernate.internal.util.StringHelper#firstIndexOfChar is only used to search org.hibernate.hql.internal.classic.ParserHelper#HQL_SEPARATORS so, maybe we should build a static set for it to avoid build the set every time.

It'd scan all string many times even if it starts with stop character.
