Which version of ElasticJob did you use?

• 0b3a6eb

Expected behavior

• Unit test DefaultJobClassNameProviderTest#assertGetLambdaJobName executes successfully on JDK 21.

Actual behavior

• Unit test DefaultJobClassNameProviderTest#assertGetLambdaJobName fails on JDK 21. Refer to Support for building with OpenJDK 21 #2270 .

Reason analyze (If you can)

• There is currently no solution. I'm still not sure what causes this unit test to fail on OpenJDK 21, and I can't find the corresponding JEP change.

Steps to reproduce the behavior.

• Null.

Example codes for reproduce this issue (such as a github link).

• Refer to https://github.com/apache/shardingsphere-elasticjob/blob/0b3a6eb993ee1abcb8ae81efa6ccaeb9b494ea5c/kernel/src/test/java/org/apache/shardingsphere/elasticjob/kernel/internal/setup/DefaultJobClassNameProviderTest.java .

@Test
@DisabledForJreRange(min = JRE.JAVA_21, max = JRE.OTHER)
void assertGetLambdaJobName() {
    JobClassNameProvider jobClassNameProvider = new DefaultJobClassNameProvider();
    FooJob lambdaFooJob = shardingContext -> {
    };
    String result = jobClassNameProvider.getJobClassName(lambdaFooJob);
    assertThat(result, is("org.apache.shardingsphere.elasticjob.kernel.internal.setup.DefaultJobClassNameProviderTest$$Lambda$"));
}

• This unit test previously executed successfully on a GraalVM Native Image built with GraalVM CE 23.1.0 For JDK 21, but failed under the Hotspot JDK. As merged in [GR-47937] Make lambda class names format consistent with the JDK name format oracle/graal#7775 , this unit test fails in GraalVM Native Image built with GraalVM CE 24.0 For JDK 22 like Hotspot JDK.

• I'm still not sure what we should do on this issue, there is an unknown JEP that breaks unit test execution.
