As the format of this heap dump is different from hprof file format this cannot be analyzed using either MAT analyzer (the eclipse plugin) or JProfiler because those prefer binary data to analyze.
There is a heap dump analyzer specially to the IBM VM called 'IBM Thread and Monitor Dump Analyzer for Java'. You can download the jar from here. (Please note that this version works with only JDK 7). Then you can simply run the jar file using this command
chanika@chanika-ThinkPad-T530:/apps/jdk1.7.0/bin$ ./java -jar /home/chanika/Downloads/jca445.jar
Then you will get a window as following
Click on File -> Open Thread Dumps -> Brows the thread dump file and select that.
Then that file will come under thread dump list and the when you select the dump file from the list some information in the header will appear as following screenshot
Then you can analyze the thread dump using options in 'Analyze' tab. This is a sample thread dump analyze I have done.
