JavaParser finds "." in place of first element after a yeild statement. about javaparser HOT 14 CLOSED

Your test case can be reduced to the following.

There seem to be 2 problems:
The label parsing which does not tolerate the '.' character;
The parsing of the expression which does not tolerate a negative integer;

@Test
void issue4400() {
	String code =
			"enum LEVEL {\r\n"
			+ "		LOW, MEDIUM, HIGH;\r\n"
			+ "	}\r\n"
			+ "	\r\n"
			+ "	public class Foo {\r\n"
			+ "		public static int match(LEVEL level) {\n"
			+ "	          return switch (level) {\n"
			+ "			default -> throw new UnsupportedOperationException();\n"
			+ "			case LEVEL.LOW -> -1;\n"
			+ "		  };\n"
			+ "		}\n"
			+ "	}";
	JavaParser javaParser = new JavaParser();
	javaParser.getParserConfiguration().setLanguageLevel(ParserConfiguration.LanguageLevel.RAW);
	ParseResult<CompilationUnit> result = javaParser.parse(code);

	if (!result.isSuccessful()) {
		for (Problem problem : result.getProblems()) {
			System.out.println(problem.getMessage());
		}
	}

}

Code formatting doesn't do it justice, here's a picture with an I-beam indicating the exact place:

Can you provide us with a unit test?

Can you provide us with a unit test?

Would the code being parsed suffice? I don't really know how to setup a unit test for this

The program is using the latest version of JavaParser available on maven-central (3.25.10)

Thank you. Can you show us how you configure the parser.

I get no exceptions when I parse your class with this code snippet.

JavaParser javaParser = new JavaParser();
javaParser.getParserConfiguration().setLanguageLevel(ParserConfiguration.LanguageLevel.RAW);
ParseResult<CompilationUnit> result = javaParser.parse(code);

Very weird, it seems to work standalone for me too....

nevermind, result.isSuccessful() is not true

This problem seems to have been solved in the current version javaparser-parent-3.26.0-snapshot

from javaparser.

I'm closing this issue as it seems to have been resolved.
