[ https://issues.jboss.org/browse/TEIIDDES-2782?page=com.atlassian.jira.plu... ] Paul Richardson commented on TEIIDDES-2782: ------------------------------------------- [~blafond] Testing / debugging brings the following conclusions: # Adding a t == null check at the top of Teiid9ParserTokenManager.calculateOffset (can be added into jjt file for permanence) mitigates the parser error. This, I think has to be the most appropriate fix since everything in that method requires the presence of a token. I am not sure there is much else that can be done about these '\r'. Trying to duplicate this with '\n' or '\t' seems impossible and even copying the text into notepad then into the editor works fine. # Whether the fix above is added or not, the comment handling still breaks in various situations and performs oddly, despite there being several quite complex unit tests in TestQuery9Parser. All the unit tests pass but there still remains an issue with comments moving around and disappearing. This, I think, represents an unrelated bug that would need to be investigated separately. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
