@lkishalmi do we have to regenerate something after updating antlr?

https://github.com/search?q=repo%3Aapache%2Fnetbeans+org.netbeans.libs.antlr4.runtime+language%3Axml&type=code its used in many places. Probably better to run all tests at least once before integration.

edit: all tests were green

Well, AFAIK, we've changed the build to generate Lexers/Parsers during build time, with the actual ANTLR version in most of the cases.

On the top of my head it's the tomlj that could be an issue and we might need to roll a new toml-java as well.

I did a parallel build an only spot the following difference

< // Generated from ANTLRv4Parser.g4 by ANTLR 4.13.1
---
> // Generated from ANTLRv4Parser.g4 by ANTLR 4.13.2

< @SuppressWarnings({"all", "warnings", "unchecked", "unused", "cast", "CheckReturnValue"})
---
> @SuppressWarnings({"all", "warnings", "unchecked", "unused", "cast", "CheckReturnValue", "this-escape"})

<       static { RuntimeMetaData.checkVersion("4.13.1", RuntimeMetaData.VERSION); }
---
>       static { RuntimeMetaData.checkVersion("4.13.2", RuntimeMetaData.VERSION); }

thanks for diffing the generated code to verify! update looks good to me.

btw, good job catching all old versions which were overlooked in past updates
