    Description


      This option was added in JDK7 as a migration path to use parallel capable class loaders.

      -XX:+UnlockDiagnosticOptions -XX:+UnsyncloadClass
      > EXTREMELY UNSAFE
      > DEPRECATED (default false)
      > Declares all class loaders as parallel capable
      > Allows parallel defineClass: 1st definer succeeds, others
      use first's results [*different from parallel capable]
