-Dcom.ibm.dbgmalloc

This option provides memory allocation diagnostic information for class library native code.

-Dcom.ibm.dbgmalloc=true

When an application is started with this option, a javadump records the amount of memory allocated by the class library components. You can use this option together with the -Xcheck:memory option to obtain information about class library call sites and their allocation sizes. Enabling this option has an impact on throughput performance. For sample javadump output, see Native memory (NATIVEMEMINFO).
