From d646ae0a73deb0d80792a6a9c0757317ad8049c5 Mon Sep 17 00:00:00 2001 From: Stephane Eranian Date: Tue, 16 Feb 2016 07:37:41 +0100 Subject: [PATCH] perf jvmti: Add check for java alternatives cmd in Makefile This patch modifies the jvmti makefile to check if the /usr/sbin/java-update-alternatives utility is present. If so, then use it, if not then use the altenatives command. This helps handle the difference between Ubuntu and Fedora Linux distributions.
