        Description

        Use the attached JFRDynamicCDS.java test case:

        $ rm -rf JFRDynamicCDS.tmp
        $ mkdir -p JFRDynamicCDS.tmp
        $ javac -d JFRDynamicCDS.tmp JFRDynamicCDS.java
        $ jar cvf JFRDynamicCDS.jar -C JFRDynamicCDS.tmp .

        $ java -cp JFRDynamicCDS.jar -Xlog:cds -XX:ArchiveClassesAtExit=JFRDynamicCDS.jsa JFRDynamicCDS
        ==> CRASH

        $ java -cp JFRDynamicCDS.jar -Xlog:cds -XX:ArchiveClassesAtExit=JFRDynamicCDS.jsa JFRDynamicCDS 0
        ==> no crash

        $ java -cp JFRDynamicCDS.jar -Xlog:cds -XX:ArchiveClassesAtExit=JFRDynamicCDS.jsa JFRDynamicCDS 1
        ==> CRASH

        So -XX:ArchiveClassesAtExit would crash if the app simply does:
             RecordingStream rs = new RecordingStream();
             rs.close();

        This crash is observable only with JDK 17. JDK 16 is OK.
