当我TomCat在其上使用已部署的 webProject 运行时。我开始收到异常，这一直在杀死并重新启动我的项目。我不知道在哪里搜索问题，也许有人可以帮助我。

SEVERE: The web application [ROOT] created a ThreadLocal with key of type [scala.concurrent.forkjoin.ThreadLocalRandom$1] (value [scala.concurrent.forkjoin.ThreadLocalRandom$1@5c1e8d8a]) and a value of type [scala.concurrent.forkjoin.ThreadLocalRandom] (value [scala.concurrent.forkjoin.ThreadLocalRandom@28aae326]) but failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak.
