Header for -agentlib:hprof (or -Xrunhprof) ASCII Output (JDK 5.0 JVMTI based)  WARNING! This file format is under development, and is subject to  change without notice.  This file contains the following types of records:  THREAD START  THREAD END mark the lifetime of Java threads  TRACE represents a Java stack trace. Each trace consists   of a series of stack frames. Other records refer to   TRACEs to identify (1) where object allocations have   taken place, (2) the frames in which GC roots were   found, and (3) frequently executed methods.  HEAP DUMP is a complete snapshot of all live objects in the Java   heap. Following distinctions are made:   ROOT root set as determined by GC   CLS classes   OBJ instances   ARR arrays  SITES is a sorted list of allocation sites. This identifies   the most heavily allocated object types, and the TRACE   at which those allocations occurred.  CPU SAMPLES is a statistical profile of program execution. The VM   periodically samples all running threads, and assigns   a quantum to active TRACEs in those threads. Entries   in this record are TRACEs ranked by the percentage of   total quanta they consumed; top-ranked TRACEs are   typically hot spots in the program.  CPU TIME is a profile of program execution obtained by measuring   the time spent in individual methods (excluding the time   spent in callees), as well as by counting the number of   times each method is called. Entries in this record are   TRACEs ranked by the percentage of total CPU time. The   "count" field indicates the number of times each TRACE   is invoked.  MONITOR TIME is a profile of monitor contention obtained by measuring   the time spent by a thread waiting to enter a monitor.   Entries in this record are TRACEs ranked by the percentage   of total monitor contention time and a brief description   of the monitor. The "count" field indicates the number of   times the monitor was contended at that TRACE.  MONITOR DUMP is a complete snapshot of all the monitors and threads in   the System.  HEAP DUMP, SITES, CPU SAMPLES|TIME and MONITOR DUMP|TIME records are generated  at program exit. They can also be obtained during program execution by typing  Ctrl-\ (on Solaris) or by typing Ctrl-Break (on Win32).
