com.oracle.ojdbc:ojdbc8 vs com.oracle.database.jdbc:ojdbc8 - what's the difference?

Question

Using both in different modules of the application we faced the FAN issue: ERROR: attempt to configure ONS in FanManager failed with oracle.ons.NoServersAvailable: Subscription time out We're going to resolve it with the well-known recipe:

implementation("com.oracle.ojdbc:ojdbc8:19.8.0.0"){
    exclude(group = "com.oracle.ojdbc", module = "simplefan")
    exclude(group = "com.oracle.ojdbc", module = "ons")
}

But it should be understood the difference to unificate. What's the difference? Thx!
