In cds/appcds/javaldr/AnonVmClassesDuringDump.java, the setting of dynamicMode is incorrect. It is always false.

public static final boolean dynamicMode =
        Boolean.getBoolean(System.getProperty("test.dynamic.cds.archive", "false"));

The correct way should be:
       Boolean.getBoolean("test.dynamic.cds.archive")

Or it could just be:
      CDSTestUtils.DYNAMIC_DUMP

After correcting the setting, we noticed the behavior is the same regardless of dynamicMode, i.e. only the following check passed:
output -> output.shouldNotMatch(pattern)

For the last test which checks the content of the archive, there are classes in the Shared Lambda Dictionary such as java.lang.module.ModuleFinder$2$$Lambda/0x800000023
so no point to run the test on the archive content.

Removing the entire test.
