I wish this help you I think you can use Java Concurrency Framework, which comes with JDK. http://java.sun.com/j2se/1.5.0/docs/guide/concurrency/

Using new xmlns.jcp.org namespace on composites causes java.lang.NullPointerException at java.util.concurrent.Concurrent

Using new xmlns.jcp.org namespace on composites causes java.lang.NullPointerException at java.util.concurrent.Concurrent

This might help you The way how the new xmlns.jcp.org XML namespaces are been handled is broken in the first Mojarra releases 2.2.0 and 2.2.1. It has been fixed in Mojarra 2.2.2 (note: ticket in the link describes different problem symptom, but under the covers, it's essentially the same cause). It's recommended to upgrade to at least Mojarra 2.2.2 (always pick the newest available, if possible). GlassFish 4.0 has 2.2.0 bundled. You can get the JAR from javaserverfaces.java.net. All you need to do is to replace javax.faces.jar file in GlassFish's /modules folder with the newer version.
The Java EE 7 tutorial itself is fine. It was just the implementation which was broken. This kind of trouble is by the way not unusual with the very first major GlassFish release (all hastle to get it ready on time). I recommend to wait with Java EE 7 until GlassFish 4.0.1 or 4.1 has been brought out to avoid future surprises. Note that other vendors like Apache Tomcat and JBoss AS take their time to release a Java EE 7 container; they don't have a production ready version yet.

I hope this helps . Python code - Uses a multiprocessing pool and maps an array of strings. On each item in the array, a partial function is used to call a callback_function: , Your Python example looks like this in Java:
code :
stringList.parallelStream()
    .map((str) -> callbackFunction.apply(arg1, arg2, str));
int arg1 = 10;
String arg2 = "foo";
Function<String, String> partialFunction = (str) -> callbackFunction.apply(arg1, arg2, str);
stringList.parallelStream().map(partialFunction);

I wish did fix the issue. Solved! I was adding Kotlin standard library to the the module that uses the Kotlin but not in the module that was using this module. Adding the library to the main module as well solved the issue.

this will help As the error says, you are out of heap space. Try to provide more heap by giving following JVM argument when starting tomcat:

like below fixes the issue One of the most versatile means for threads to communicate is a BlockingQueue.
In your case, you have one thread that creates a "response" (i.e., a producer), and you have another thread that is waiting for the "response" (a consumer). One way to implement that is for the producer to put() the response into a BlockingQueue, and have the consumer take() the response out of the queue.
