Descrizione

### Description

I'm not sure this is a Colima bug. It might be a qemu issue or something else, but I'm not sure where else to start. Running javac from a regular OpenJDK build segfaults on a semi-regular basis.

### Version

```
colima version 0.9.1
git commit: 0cbf719f5409ce04b9f0607b681c005d2ff7d94a

runtime: docker
arch: aarch64
client: v25.0.4-rd
server: v28.3.3
limactl version 1.2.1
qemu-img version 10.0.3
Copyright (c) 2003-2025 Fabrice Bellard and the QEMU Project developers
```

### Operating System

- [ ] macOS Intel <= 13 (Ventura)
- [ ] macOS Intel >= 14 (Sonoma)
- [ ] Apple Silicon <= 13 (Ventura)
- [x] Apple Silicon >= 14 (Sonoma)
- [ ] Linux

### Output of `colima status`

```
INFO[0000] colima [profile=intel] is running using macOS Virtualization.Framework
INFO[0000] arch: x86_64
INFO[0000] runtime: docker
INFO[0000] mountType: virtiofs
INFO[0000] docker socket: unix:///Users/mike/.colima/intel/docker.sock
INFO[0000] containerd socket: unix:///Users/mike/.colima/intel/containerd.sock
```

### Reproduction Steps

```
colima start --cpus=8 --memory=32 intel
colima -p intel ssh
$ sudo apt install openjdk-25-jdk
$ cd /tmp
$ cat <HelloWorld.java
class HelloWorld {
public static void main(String[] args) {}
}
$ for i in $(seq 1 100); do echo $i; javac HelloWorld.java; done
```

leads to javac segfaulting on about one run in five. The exact location and nature of the crash varies from run to run. Occasionally I've seen a SIGILL, so it looks like it's jumping into an invalid pointer.

Needless to say, `javac` can compile Hello World just fine on a normal Intel machine. The bug is not upstream.

I've attached the hotspot crash log. It dies trying to access `0x0000000ca8abf7bb` which is not even close to being something that's mapped.

What's a good way to start debugging this?
