        public void run() {
            // Read all the .com and jetpack sites and get the list of home URLs.
            // This will be used later to check if the user is a member of followers blog marked as private.
            List<SiteModel> sites = mSiteStore.getWPComAndJetpackSites();
            for (SiteModel site : sites) {

    //wait until the task is running
    task.awaitExecutionStarted();
    //attempt to start execution from the test thread. this execution should be skipped -> it won't block

use of java.util.concurrent.ThreadPoolExecutor in project spring-framework by spring-projects.

the class ThreadPoolExecutorFactoryBean method initializeExecutor.

@Override

Example 40 with ThreadPoolExecutor

use of java.util.concurrent.ThreadPoolExecutor in project spring-framework by spring-projects.

the class ThreadPoolTaskExecutor method initializeExecutor.

/**
	 * Note: This method exposes an {@link ExecutorService} to its base class
	 * but stores the actual {@link ThreadPoolExecutor} handle internally.
