Meaning of square bracket in java stacktrace

Question

I encountered below error. I can solve NosuchMethodError by changing some of the dependency in gradle file.

Caused by: java.lang.NoSuchMethodError: io.netty.util.internal.PlatformDependent.safeConstructPutInt(Ljava/lang/Object;JI)V
    at io.netty.util.internal.ReferenceCountUpdater.setInitialValue(ReferenceCountUpdater.java:67) ~[netty-common-4.1.79.Final.jar:4.1.33.Final]

    at io.netty.util.internal.ObjectPool$RecyclerObjectPool$1.newObject(ObjectPool.java:77) ~[netty-common-4.1.79.Final.jar:4.1.33.Final]

But I wonder what is the meaning of square bracket. It seems like that there are two jar files are included.

~[netty-buffer-4.1.33.Final.jar:4.1.79.Final]

In this case which dependency will be used in run time?
