11/09/2023, 1:51 PMOk, I installed Eclipse Temurin jdk-17.0.9+9. Fortunately it's giving out additional stack trace. OpenJdk 11 somehow din't give out this info.
java.lang.NoClassDefFoundError: Could not initialize class org.apache.druid.query.QueryRunnerTestHelper
Caused by: java.lang.ExceptionInInitializerError: Exception java.lang.IllegalStateException: NullHandling module not initialized, call NullHandling.initializeForTests() [in thread "main"]
Any ideas why NullHandling is not being initialized?
Here is the build debug logs.

11/09/2023, 6:24 PMseems like a test case problem. The one writing the test has to initialize it. Which class is causing this? And I don’t know why this is causing an issue while running the program

11/10/2023, 10:57 AM@Laksh Singla I have attached the build failure logs in my previous message. Many test cases are failing.
For ex: SchemaEvolutionTest, DefaultQueryMetricsTest, ResultGranularTimestampComparatorTest and many more testcases fails.

11/10/2023, 2:22 PMHi @Gian Merlino, Can you help me out with these build errors. My brief lookup at the code indicates that the Testcases are missing explicit calls to initialization of NullHandling. They are being initialized in a static block across many other test cases.
Wondering how are these test cases even passing in CI-Builds, or are they being ignored?
Kindly let me know if that's not the case and I have a screwed up DEV Env.
