`boolean record = true;` causes a syntax error even thought it is valid Java

Operating system

macOS/Windows/Linux?

Bug description

Adding boolean record = true; anywhere to the sketch causes the preprocess to emit an Error even though it is valid Java.

This is what I know so far:

• record is a java keyword
• changing it to boolean record1 = true; suppresses the error
• I tried changing the antlr version back to what it was defined in the Ant build system but that didn't help either

Steps to reproduce this

1. Add boolean record = true; to a sketch

2. See the preprocessor be unhappy

snippet

boolean record = true;

void setup() {

}

void draw() {
 
}

Would you like to work on the issue?

Yes, I’d like to help with this

processing4/java/preprocessor/src/main/antlr/JavaLexer.g4

Lines 109 to 110 in 275d789

	// Records
	RECORD: 'record';

Here it is defined in the Lexer

and here most of it in the Parser

processing4/java/preprocessor/src/main/antlr/JavaParser.g4

Lines 443 to 463 in 275d789

	// RECORDS - Java 17
	recordDeclaration
	: RECORD identifier typeParameters? recordHeader (IMPLEMENTS typeList)? recordBody
	;
	recordHeader
	: '(' recordComponentList? ')'
	;
	recordComponentList
	: recordComponent (',' recordComponent)*
	;
	recordComponent
	: typeType identifier
	;
	recordBody
	: '{' (classBodyDeclaration | compactConstructorDeclaration)* '}'
	;

Changing the string in the top does make the error go away but that of course moves it to a separate keyword

@Stefterv Oh I will explore this! 🤓

Cool, the antlr stuff has been an antler (pun intended) in my side for a while so it'd be nice to share this :)
