gianm opened a new issue, #17429: URL: https://github.com/apache/druid/issues/17429
We've been seeing a high degree of segfaults recently in the `processing` unit tests under JDK 21. Here's an example: https://github.com/apache/druid/actions/runs/11528594002/job/32166241444?pr=17414. The common thread is an error like this: ``` Current CompileTask: C2:1780380 144967 4 org.apache.druid.query.filter.InDimFilter::optimizeLookup (744 bytes) Stack: [0x00007f9c045fb000,0x00007f9c046fb000], sp=0x00007f9c046f6660, free space=1005k Native frames: (J=compiled Java code, j=interpreted, Vv=VM code, C=native code) V [libjvm.so+0xf15629] BoolNode::Ideal(PhaseGVN*, bool)+0x19 V [libjvm.so+0xd6258e] PhaseIterGVN::transform_old(Node*)+0x9e V [libjvm.so+0x6ba360] Conv2BNode::Ideal(PhaseGVN*, bool)+0x180 V [libjvm.so+0xd6258e] PhaseIterGVN::transform_old(Node*)+0x9e V [libjvm.so+0xd5e4a9] PhaseIterGVN::optimize()+0xf9 V [libjvm.so+0x6712cf] Compile::Optimize()+0xf9f V [libjvm.so+0x672a06] Compile::Compile(ciEnv*, ciMethod*, int, Options, DirectiveSet*)+0xf26 V [libjvm.so+0x598acb] C2Compiler::compile_method(ciEnv*, ciMethod*, int, bool, DirectiveSet*)+0x18b V [libjvm.so+0x678ee4] CompileBroker::invoke_compiler_on_method(CompileTask*)+0xca4 V [libjvm.so+0x67c0d8] CompileBroker::compiler_thread_loop()+0x6a8 V [libjvm.so+0x931f40] JavaThread::thread_main_inner()+0x1e0 V [libjvm.so+0xf86b88] Thread::call_run()+0xa8 V [libjvm.so+0xd103ba] thread_native_entry(Thread*)+0xda ``` Things that did _not_ help include: - Using Corretto instead of Zulu (#17426) - Switching off `jfr_profiler` (#17418). - Updating various test/build dependencies (#17414). Since this is in the C2 compiler, and only happens on JDK 21, it seems likely to be a JDK bug rather than something we're doing wrong. @pranavbhole has raised a support case with Azul at https://support.azul.com/hc/en-us/requests/65354. We don't have any special support contract with them, so hopefully they respond out of the goodness of their hearts. Since this issue happens on Corretto too, it's possibly a broader OpenJDK issue, so we could also consider raising a bug with OpenJDK. -- This is an automated message from the Apache Git Service.
