Let's start by looking at the error message. + +The problem occurs when running `java --version` and results in a SIGILL (illegal instruction) signal. The error points to the function __kernel_getcpu+0x8 in the file linux-vdso64.so.1. That's part of the kernel's virtual dynamic shared object, which is used for certain system calls. + +SIGILL usually means an illegal or unrecognized machine instruction was executed. In this case, it's happening in a library provided by the Linux kernel (vdso), so that suggests something is wrong with how the kernel is handling these instructions. + +Looking deeper, since it's on an s390x architecture, which is IBM Z/Architecture, there might be specific CPU features or instruction sets being used. The Java runtime might be trying to use a feature that isn't supported in user-mode, but since vdso is part of the kernel, this could relate to system-level issues. + +The fact that it's in the vdso indicates it's not just a regular library but something provided by the kernel for efficient system calls. If the instruction causing the crash is at an offset within __kernel_getcpu, perhaps the guest CPU doesn't support that particular opcode when running under QEMU virtualization. + +QEMU might be emulating some instructions incorrectly or failing to pass through certain features required by the Java runtime on s390x. This could be a problem with how QEMU is handling the CPU model or the instruction set extensions needed for this specific operation. + +Since the issue arises in the kernel's vdso and involves an illegal instruction, it seems more related to system-level operations rather than user applications. The JVM isn't doing anything wrong; it's just encountering an unexpected situation when interacting with the kernel's services. +</think> + +system \ No newline at end of file |
