Subject [jira] [Commented] (FLEX-35183) Unclosed comment in MXML leads to infinite loop in compiler
Date Tue, 22 Nov 2016 21:31:59 GMT

    [ https://issues.apache.org/jira/browse/FLEX-35183?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15687958#comment-15687958

Josh Tynjala commented on FLEX-35183:
-------------------------------------

I spent an afternoon trying to figure this out by connecting a debugger. I think I understand
what's wrong, but I would need to learn more about JFlex to figure out how to fix it. It appears
that the code generated by RawMXMLTokenizer.lex doesn't know to break out of a loop in certain
situations. It just continues looping if a comment is open and it reaches the end of the file.
Basically, just reading the EOF over and over again.

I assume it's the same with the unclosed CDATA in FLEX-35184, but I did not specifically check
in the debugger for that one.
