Currently, in Oracle tier4-rt-appcds-dynamic, we run with

jtreg -Dtest.dynamic.cds.archive=true test/hotspot/jtreg:hotspot_appcds_dynamic

However, some JDK builds (e.g., cross-compiled aarch64 builds) may include a default CDS archive (usually found under $JAVA_HOME/lib/server/classes.jsa). This causes failures like:

-----------
 stdout: [Error occurred during initialization of VM
Unable to use shared archive.
];
 stderr: [An error has occurred while processing the shared archive file.
Specified shared archive not found (/test/jdk-15/fastdebug/lib/server/classes.jsa).
]
 exitValue = 1

java.lang.RuntimeException: 'Written dynamic archive' missing from stdout/stderr
