The Last Frontier in Java Performance: Remove the Garbage Collector
A new JEP draft has been filed to create a no-op garbage collector: a GC that doesn't actually reclaim memory. This is aimed at aiding JVM implementers and researches and, to a lesser extent, ultra-performant applications that generate little to no garbage. If the JEP goes ahead, the new GC would be available together with the existing ones, and would have no effect unless explicitly activated.

Java 9 Will Adjust Memory Limits if Running with Docker
A first experimental change has been added to Java 9 so the JVM can understand that it is running within a container and adjust memory limits accordingly. Despite the increase in popularity of containers, many tools, including the JVM, still rely on the host's parameters to assess available resources, oftentimes running out of memory. This change tries to prevent many of those scenarios.

Oracle Paves the Way to Standardise Command Line Options in the JDK
Oracle has created JEP 293 to introduce a set of guidelines for command line options in JDK tools in an attempt to fix the existing disparity among them. The JEP has no target version yet, meaning it will be delivered with Java 10 as soonest; however, taking into account that the scope is only to create a set of guidelines for new options, it may take even longer for the effects to be felt.
