JDK23: Alpine Linux: hotspot_runtime_0 timeouts

**Summary**
The test target hotspot_runtime_0 (part of extended.openjdk) is running far too long and timing out, but only on JDK
23 for Alpine Linux.

**Details**
On JDK21, this target takes about 6 minutes. On JDK23, it always appears to run until timeout. This can be an hour or 18.

I dug through several instances of this test, and cannot find a single instance that passed.

Start with the failed CI console logs for hotspot_runtime_0 in the extended.openjdk target, comparing the JDK23 Alpine runs with the passing JDK21 run linked in the issue. Trace why the JDK23 target does not complete on Alpine; done means the target finishes within its timeout and the relevant test run passes.
