Log4j2.properties scripts and JavaScript error version > 8.0

From version 8.0.0 JavaScript in log4j2.properties rise error.

elastic/logstash/blob/8.0/logstash-core/lib/logstash/runner.rb#L447

      
        
              end
              return 1
            ensure
              Stud::untrap("INT", sigint_id) unless sigint_id.nil?
              Stud::untrap("TERM", sigterm_id) unless sigterm_id.nil?
              Stud::untrap("HUP", sighup_id) unless sighup_id.nil?
              FileLockFactory.releaseLock(@data_path_lock) if @data_path_lock
              @log_fd.close if @log_fd
            end # def self.main
            
            
def log_configuration_contains_javascript_usage?
               context = LoggerContext.getContext(false)
               config = context.configuration
               config_file = config.configuration_source.file
               # no config file so nothing to check
               return false if config_file.nil?
            
            
   logger.info("Log4j configuration path used is: #{config_file.path}")
               log_config = File.open(config_file.absolute_path).read
               (log_config =~ /^[^#]+script\.language\s*=\s*JavaScript/) != nil
            end

So i tryed find any script to filter logs with enabled pipeline splitting (pipeline.separate_logs: true), but dont found any replacement for code (worked before version 8.0.0):

appender.json_rolling.avoid_pipelined_filter.type = ScriptFilter
appender.json_rolling.avoid_pipelined_filter.script.type = Script
appender.json_rolling.avoid_pipelined_filter.script.name = filter_no_pipelined
appender.json_rolling.avoid_pipelined_filter.script.language = JavaScript
appender.json_rolling.avoid_pipelined_filter.script.scriptText = ${sys:ls.pipeline.separate_logs} == false || !(logEvent.getContextData().containsKey("pipeline.id"))

appender.routing.routes.script.type = Script
appender.routing.routes.script.name = routing_script
appender.routing.routes.script.language = JavaScript
appender.routing.routes.script.scriptText = logEvent.getContextData().containsKey("pipeline.id") ? logEvent.getContextData().getValue("pipeline.id") : "sink";

Did anybody knows how i can replace script to separate pipelines in logstash without JavaScript?
