Examples with ContextManagerProvider org.eclipse.microprofile.context.spi.ContextManagerProvider used on opensource projects

Example 1 with ContextManagerProvider

use of org.eclipse.microprofile.context.spi.ContextManagerProvider in project quarkus by quarkusio.

the class SmallRyeContextPropagationRecorder method configureRuntime.

public void configureRuntime(ExecutorService executorService, ShutdownContext shutdownContext) {
    // associate the static init manager to the runtime CL

    SmallRyeContextManager contextManager = builder.build();
    contextManagerProvider.registerContextManager(contextManager, Thread.currentThread().getContextClassLoader());
    // needs to be late, as running threads can re-create an implicit one
    shutdownContext.addLastShutdownTask(new Runnable() {

        @Override
        public void run() {
            contextManagerProvider.releaseContextManager(contextManager);
