I am seeing new failures on aarch64 only. x64 seems fine:


runtime/cds/appcds/applications/JavacBench.java#leyden			macosx-aarch64-debug
runtime/cds/appcds/applications/MicronautFirstApp.java#leyden		macosx-aarch64-debug
runtime/cds/appcds/applications/MicronautFirstApp.java#leyden		linux-aarch64-open
runtime/cds/appcds/applications/MicronautFirstApp.java#leyden		linux-aarch64-debug
runtime/cds/appcds/applications/QuarkusGettingStarted.java#leyden       linux-aarch64-debug


Here's the hs_err. This happens in the final production run.
