Example codes for reproduce this issue (such as a github link).

Start multiple processes of the following codes.

JobConfiguration jobConfiguration = JobConfiguration.newBuilder("oneoff", 32)
        .overwrite(true)
        .failover(true)
        .build();
OneOffJobBootstrap oneOffJobBootstrap = new OneOffJobBootstrap(REGISTRY_CENTER, (SimpleJob) shardingContext -> log.info("{}", shardingContext), jobConfiguration);
for (;;) {
    oneOffJobBootstrap.execute();
}

The Quartz thread was keep consuming CPU.
