Java version updates typically change GC behavior. If one has highly tuned setup there is no guarantee that a newer version would not regress. Another problem is crashes. Java runtime is highly reliable, but still bugs happens.

Are you talking about performance or behaviour? I’ve never seen an issue caused by a GC.

  Latency spikes are the issue. Modern Java mostly solved this, but tuning GC settings is still the thing especially when Java runs on a big server.
