After review of Java CC we feel these will be difficult to address > using that tool. Also, the .jjt files used by JavaCC are hard to understand > and maintain. > ANTLR is being reviewed as the most likely choice to move to, but other > parsers will be reviewed as well. > This JIRA will act as an umbrella issue for other parser issues. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
