The test is already quite slow in mainline because of the daemon `GarbageProducerThread` which triggers massive GC activity. With `--enable-preview` the jimage paths, including preview directory processing in `src/java.base/share/classes/jdk/internal/jimage/ImageReader.java`, are all C2 compiled due to `-Xcomp` and while that happens, the daemon thread keeps issuing synchronous explicit GCs accumulating ~223 extra Full GCs and ~15.6s extra Full-GC pause times.
While this overhead of `jimage` is a more general issue, there's no real benefit in running this particular test with `-Xcomp` (even without Valhalla). So let's exclude it.
