> This is important because Bits.reserveMemory calls System.gc() hoping to free native
memory in order to avoid throwing an OutOfMemoryException. This call is currently a no-op
due to -XX:+DisableExplicitGC.
> It's worth mentioning that -XX:MaxDirectMemorySize can be used to increase the amount
of native memory available for allocation of direct byte buffers.
> Hongyuan Li pointed out the issue with the usage of -XX:+DisableExplicitGC in: https://issues.apache.org/jira/browse/KAFKA-5444?focusedCommentId=16054129&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16054129
