[SUREFIRE-2200] JEP 443: Illegal field name "" in class

• Type: Bug

• Affects Version/s: 3.1.2
• Component/s: Maven Surefire Plugin
• Environment: JDK 21 GA ; Maven 3.9.4 ; junit-jupiter 5.10.0 ; maven-surefire-plugin 3.1.2 ; maven-compiler-plugin 3.11.0

Description

When running a test class that makes use of JEP 443, surefire reports an Error, despite being run with --enable-preview.

[ERROR] Illegal field name "" in class com.example.Demo

Example:

class Demo {
    @Test
    public void test() {
        Function<Object, Integer> foo = _ -> 1;
        // ...
    }
}

It is worth noting, that compiler:3.11.0:testCompile completes just fine.

The maven-compiler-plugin requires <compilerArg>--enable-preview</compilerArg> and maven-surefire-plugin require <argLine>-enable-preview</argLine>.
