Description

In AgentProviderService#buildContainerLaunchContext():

    if (metainfo == null) {
      synchronized (syncLock) {
        if (metainfo == null) {
          metainfo = getApplicationMetainfo(fileSystem, appDef);

For double checked locking to work, metainfo should be declared volatile.
