Hello,
Please review the fix for: https://bugs.openjdk.java.net/browse/JDK-8169001 Webrev at: http://cr.openjdk.java.net/~ksrini/8169001/webrev.00/ Background:
Launcher ergonomics was introduced last decade to help determine if the execution system is "Server Class", this was necessary to choose server VM on platforms that supported both client and server VMs (primarily for Solaris and Linux 32-bit). The algorithm involves computing and detecting the number of CPUs and the amount of memory on the target system. All modern computers systems with hyper-threading cause the ergonomics to choose server. JDK9 Platforms that have only server vm. ./linux-x64/lib/amd64/server/libjvm.so ./linux-arm64-vfp-hflt/lib/aarch64/server/libjvm.so ./solaris-sparcv9/lib/sparcv9/server/libjvm.so ./solaris-x64/lib/amd64/server/libjvm.so ./windows-x86/bin/server/jvm.dll ./windows-x64/bin/server/jvm.dll JDK9 Platforms that have more than one vm variant: ./linux-arm32-vfp-hflt/lib/arm/client/libjvm.so (default) ./linux-arm32-vfp-hflt/lib/arm/minimal/libjvm.so ./linux-x86/lib/i386/server/libjvm.so (default) ./linux-x86/lib/i386/minimal/libjvm.so In the cases where multiple VMs are supported the ergnomics has no effect, and the default platforms are chosen by the jvm.cfg. Thus the launcher ergonomics is obsolete and redundant.
Thanks Kumar
