If you are looking at a recording of JRockit J2SE 5.0 or later, the recording includes information about native locks (Figure 13-4). Native locks are locks in the JRockit internal code and is nothing your application can control.
Use the filtering function to find the Java locks you are looking for, see Filtering Information.
If you find high contention on a JRockit internal lock that might be causing issues for your application, either contact BEA support or contact JRockit through the BEA JRockit Newsgroup at the dev2dev web site.
Lock profiling data can only be generated from the command line. If you have no information displayed in the Locks tab, the native sampling was not enabled during the recording. See 3. Create JRA Recording for information on how to enable native sampling.
