This is a consequence of the switch to the Unified Logging system for logging of GC related messages. There are quite a few -XX options that have disappeared, more detail can be found here:

https://bugs.openjdk.java.net/browse/JDK-8145092

You will need to remove the -XX:+PrintHeapAtGC flag. There is a bug on the Solr JIRA for this:
