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 -- This message was sent by Atlassian JIRA (v6.4.14#64029)
