JRuby PermGen kehabisan ruang bahkan menggunakan objek Java dalam kode Ruby

Keterangan:

Jika kita menggunakan objek Java jruby, dapatkan permgen juga:

System.out.println("Initialazing..");
//Spring applicaton context
WebApplicationContext wac = (WebApplicationContext) AppContext.getApplicationContext();
// prepare path to internal ruby 
String scriptsPath = wac.getServletContext().getRealPath(RUBY_PATH);
String jrubyHome = wac.getServletContext().getRealPath("WEB-INF" + File.separator +     "jruby");
// Initializing Scripting container
ScriptingContainer container = new ScriptingContainer(isShared ?     LocalContextScope.SINGLETHREAD
            : LocalContextScope.THREADSAFE, LocalVariableBehavior.PERSISTENT);
// Configuring scriptingcontainer to avoid memory leaks
container.setCompileMode(RubyInstanceConfig.CompileMode.OFF);
System.setProperty("org.jruby.embed.compilemode", "OFF");
System.setProperty("jruby.compile.mode", "OFF");
// Setup ruby version
container.setCompatVersion(CompatVersion.RUBY1_9);
// Set jruby home
container.getProvider().getRubyInstanceConfig().setJRubyHome(jrubyHome);
List<String> loadPaths = new ArrayList<String>();
// load path
loadPaths.add(scriptsPath);
container.getProvider().setLoadPaths(loadPaths);
// ruby dispatcher initializing and run in simple mood
String fileName = scriptsPath + File.separator + "dispatcher_fake.rb";
// run scriplet
container.runScriptlet(PathType.ABSOLUTE, fileName);
// terminate container to cleanup memory without any effects
container.terminate();
container=null;

naskah:

ENV['GEM_PATH'] = File.expand_path('../../jruby/1.9', __FILE__)
ENV['GEM_HOME'] = File.expand_path('../../jruby/1.9', __FILE__)
ENV['BUNDLE_BIN_PATH'] = File.expand_path('../../jruby/1.9/gems/bundler-1.0.18/bin/bundle', __FILE__)

module JavaListing
  include_package "com.util.listing"
end

class A
  include JavaListing
  def run
    1000.times do |index|
      puts "iterating #{index}"
      # java class property
      prop = JavaListing::Property.new
      prop.proNo = 111
      prop.remoteID = "1111"
      prop.ownerID = "1111"
      prop.advertiserID = "1111"
      prop.title = "Atite"
      prop.summary = "Asummury"
      prop.description = "Adescription"
      # prop.images << JavaListing::Image.new("111", "Acaption")
      prop.lat = 12.23
      prop.lng = 13.21
      #prop.address = JavaListing::Address.new("Acity", "Acountry")
      prop.location = "Alocation"
      prop.policy = JavaListing::Policy.new("AcheckinAt", "AcheckoutAt")
      prop.surfaceArea = "Asurfscearea"
      # prop.notes[index] = JavaListing::Note.new("Atitle", "Atext")
      prop.order = "Aorder"
      prop.map = JavaListing::Map.new(true, 14)
      # 
      doc = Jsoup.parse("<root><elements><element>Application Error  #{index}  </element></elements></root>")
  end

Seperti yang Anda lihat, kami menggunakan semua objek Java tetapi Perm mengatasi kebocoran memori masih terjadi

Jika kita membuat objek di aplikasi pegas dan meneruskan Konteks Aplikasi ke Ruby untuk mendapatkan kacang di masa mendatang, ini tidak menyelesaikan masalah ini

Dalam wadah skrip, atur konteks ApplicationContext = Konteks aplikasi pegas

container.put("$context", context);

kode rubi

bean = $context.getBean("some_name")
bean.myMethod()
