1Java - DTracing Java 2 3 These scripts trace the JVM, and require the Java hotspot provider which 4 was shipped with Java starting with version 1.6.0. 5 6 Some of these scripts measure method and object events, and require 7 the Java process to be run using the "+ExtendedDTraceProbes" flag. 8 For example, 9 10 java -XX:+ExtendedDTraceProbes classfile 11 12 The ExtendedDTraceProbes flag is not on by default to avoid the additional 13 overhead for maintaining these additional probes.
