JDK-8316526 - ciReplay fails with "tag mismatch: wrong class files?" when CDS is disabled
Description
When running tests in test/hotspot/jtreg/compiler/ciReplay with --enable-preview, some tests fail. Failures are not 100% reproducible, but those tests reliably pass when -enable-preview is not used.

Example of failed run:

Comments
This is a duplicate of mainline bug JDK-8316526 because '--enable-preview' used to disable CDS: Java(TM) SE Runtime Environment (fastdebug build 23-lworld5ea-2024-07-15-1824107.frederic.parain.valhalla) Java HotSpot(TM) 64-Bit Server VM (fastdebug build 23-lworld5ea-2024-07-15-1824107.frederic.parain.valhalla, mixed mode) With more recent builds of Valhalla, CDS is enabled even with '--enable-preview'.
