Can you extract the value of the lines from the IBM PHD java heap dump?

I have a heap dump of a PHD file from IBM jvm and I want to examine the values ​​of some lines. With hprof Sun JVM binary dumps it is possible, but I have not been able to recover this information from the IBM dump.

I tried:

• Eclipse Memory Analyzer (0.8.0.200906170940) with IBM DTFJ Portal Heap Dump Reader (1.3.0.200903241644)
• IBM Support Assistant (3.1.0.00) with Java Memory Dump Diagnostics (2.0.0.3b)
• Running "lines" over a dump file
• Convert to text dump with com.ibm.jvm.ras.findroots.PrintHeapdump from svcdump.jar found in mdd4j (2.0.0.3b)

In Eclipse Memory Analyzer, I can view a char array inside a String, but all entries in the array are null. I also don't see any primitive attributes for any objects.

IBM hints that they store primitive values ​​at http://www-01.ibm.com/support/docview.wss?rs=180&uid=swg21190476

This is made possible by using the Java DataOutputStream class, which allows you to output primitive Java data types in a portable binary format.

I am using Java 5.0:
