org.jboss.profiler.jvmti.JVMTIInterface.compareInventories()
It will return true if the comparisson didn't represent any changes. This can be used by JUnitTests to validate the consumption of the memory is on the expected results. @param reportOutput You could set System.out here. The location where logging information is going to be sent. @param map1 The first snapshot. @param map2 The second snapshot. @param ignoredClasses Classes you want to ignore on the comparisson. Used to ignore things you know are going to be produced and you don't have control over the testcase. @param prefixesToIgnore Same thing as classes, but every classes starting with these prefixes are going to be ignored. @param expectedIncreases An array of InventoryDataPoint with the maximum number of instances each class could be generating. @return true if the assertion is okay
