Performance on large grammar files is not so good

I'm working on the jsqlparser, and editting the jjt in Intellij with the javacc plugin, makes my laptop go 100% cpu usage for over a minute.

The file itself:
https://github.com/JSQLParser/JSqlParser/blob/master/src/main/jjtree/net/sf/jsqlparser/parser/JSqlParserCC.jjt

I'm on the latest intellij ultimate (2022.2) and plugin version: 1.10

Hi, I just profiled the plugin on your grammar. I think the problem is in that the java injection is slow (the injected Java file is very large). A workaround is to switch the injection level to "Partial" in Settings > Languagues and Frameworks > JavaCC, that improves the situation for me at least. I'm not sure what else I can do to improve this.

Thanks for the quick reply. Unfortunately, it already is "Partial". I'll try turning it off as well.

Setting to 'Disabled' keeps it working reasonably. Thanks for the tip!
