I'm trying to sync up the loom repo to jdk-19+8 (which has the commit for JDK-8280842) and running into something in this same area. So far only seeing it with the test java/foreign/TestSegmentCopy.java where the compiler broker hits this assert: # # A fatal error has been detected by the Java Runtime Environment: # # Internal Error (/workspace/open/src/hotspot/share/utilities/growableArray.hpp:145), pid=28444, tid=29083 # assert(0 <= i && i < _len) failed: illegal index # # JRE version: Java(TM) SE Runtime Environment (19.0) (fastdebug build 19-internal+0-2022-02-03-0748181.alan.bateman.loom-merge) # Java VM: Java HotSpot(TM) 64-Bit Server VM (fastdebug 19-internal+0-2022-02-03-0748181.alan.bateman.loom-merge, mixed mode, sharing, tiered, compressed oops, compressed class ptrs, g1 gc, linux-amd64) # Problematic frame: # V [libjvm.so+0x97caca] GrowableArrayView<ciTypeFlow::Block*>::at(int)+0x3a # : Current CompileTask: C2: 10015 1829 % ! 4 org.testng.internal.Invoker::invokeTestMethods @ 612 (1101 bytes) Stack: [0x00007ffa316f7000,0x00007ffa317f8000], sp=0x00007ffa317f46c0, free space=1013k Thread 0x00007ffa00e49f90 [29083] Native frames: (J=compiled Java code, j=interpreted, Vv=VM code, C=native code) V [libjvm.so+0x97caca] GrowableArrayView<ciTypeFlow::Block*>::at(int)+0x3a V [libjvm.so+0x974fba] ciTypeFlow::profiled_count(ciTypeFlow::Loop*)+0x1aa V [libjvm.so+0x97577b] ciTypeFlow::Loop::sorted_merge(ciTypeFlow::Loop*)+0x26b V [libjvm.so+0x978dac] ciTypeFlow::build_loop_tree(ciTypeFlow::Block*)+0x1bc V [libjvm.so+0x97a702] ciTypeFlow::df_flow_types(ciTypeFlow::Block*, bool, ciTypeFlow::StateVector*, ciTypeFlow::JsrSet*)+0x612 V [libjvm.so+0x97ac4e] ciTypeFlow::flow_types()+0x41e V [libjvm.so+0x97b556] ciTypeFlow::do_flow()+0x26 V [libjvm.so+0x929251] ciMethod::get_osr_flow_analysis(int)+0x51 V [libjvm.so+0x14d65d0] Parse::Parse(JVMState*, ciMethod*, float)+0x820 V [libjvm.so+0x8a1845] ParseGenerator::generate(JVMState*)+0xd5 V [libjvm.so+0xa13fc2] Compile::Compile(ciEnv*, ciMethod*, int, Options, DirectiveSet*)+0xd82 V [libjvm.so+0x89ef68] C2Compiler::compile_method(ciEnv*, ciMethod*, int, bool, DirectiveSet*)+0x178 V [libjvm.so+0xa21cd8] CompileBroker::invoke_compiler_on_method(CompileTask*)+0xbc8 V [libjvm.so+0xa22818] CompileBroker::compiler_thread_loop()+0x408 V [libjvm.so+0x1745e3a] JavaThread::thread_main_inner()+0x1ea V [libjvm.so+0x174d1a0] Thread::call_run()+0x100 V [libjvm.so+0x148c9d4] thread_native_entry(Thread*)+0x104 I may have to create a follow-on issue to track this.
