[infinispan-issues] [JBoss JIRA] (ISPN-6085) Avoid using sun.misc.VM

Avoid using sun.misc.VM ----------------------- Key: ISPN-6085 URL: https://issues.jboss.org/browse/ISPN-6085 Project: Infinispan Issue Type: Task Components: Core Affects Versions: 8.1.0.Final Reporter: Sanne Grinovero Assignee: Sanne Grinovero Fix For: 8.2.0.Beta1, 8.2.0.Final, 8.1.1.Final The function {{org.infinispan.container.entries.PrimitiveEntrySizeCalculator.IntegerCacheConstraints.calculateMaxIntCache()}} is using {{sun.misc.VM}}. This class is being moved and "idden" in Java 9: - http://mail.openjdk.java.net/pipermail/core-libs-dev/2016-January/037853.... Could we try avoiding the need for this, or explore alternatives? One could use reflection to see if the class is available without loading it explicitly, but that still needs some sensible fallback for the case in which the class isn't available. Even if this looks like a small detail, this completely blocks the possibility to test Infinispan on Java 9.
