      Description

        We observed test/hotspot/jtreg/compiler/codecache/CodeCacheFullCountTest.java failures sometimes due to `java.lang.VirtualMachineError: Out of space in CodeCache for adapters`. The stdout contains ` full_count=1` (test expects non-zero full_count):

        stdout: [[0.195s][warning][codecache] CodeCache is full. Compiler has been disabled.
