Description

While running our tests on CI with Java 17 they failed infrequently with a SIGSEGV error.

All occurrences were related to Kryo and happened in the C2 CompilerThread.

Current thread (0x00007f1394165c00):  JavaThread "C2 CompilerThread0" daemon [_thread_in_native, id=470077, stack(0x00007f1374361000,0x00007f1374462000)]

Current CompileTask:
C2:  14251 6333       4       com.esotericsoftware.kryo.io.Input::readString (127 bytes)

The full error is attached to the ticket. I can also provide the core dump if needed.
