The code heap analysis function provides deep insights into
the inner workings and the internal state of the Java VM's
code cache - the place where all the JVM generated machine
code is stored.
This function is designed and provided for support engineers
to help them understand and solve issues in customer systems.
It is not intended for use and interpretation by other persons.

The aggregate step takes an aggregated snapshot of the CodeHeap.
Subsequent print functions create their output based on this snapshot.
The CodeHeap is a living thing, and every effort has been made for the
collected data to be consistent. Only the method names and signatures
are retrieved at print time. That may lead to rare cases where the
name of a method is no longer available, e.g. because it was unloaded.
CodeHeap committed size 2496K (2M), reserved size 120036K (117M), 2% occupied.
CodeHeap allocation segment size is 128 bytes. This is the smallest possible granularity.
CodeHeap (committed part) is mapped to 624 granules of size 4096 bytes.
Each granule takes 40 bytes of C heap, that is 24K in total for statistics data.
The number of granules is limited to 512k, requiring a granules size of at least 2048 bytes for a 1GB heap.

Note: The Top50 list of the largest used blocks associates method names
and other identifying information with the block size data.
Method names are dynamically retrieved from the code cache at print time.
Due to the living nature of the code cache and because the CodeCache_lock
is not continuously held, the displayed name might be wrong or no name
might be found at all. The likelihood for that to happen increases
over time passed between analysis and print step.

Note: in this context, a gap is the occupied space between two free blocks.
Those gaps are of interest if there is a chance that they become
unoccupied, e.g. by class unloading. Then, the two adjacent free
blocks, together with the now unoccupied space, form a new, large
free block.

Use this information to judge how likely it is that a large(r) free block
might get created by code cache sweeping.
If all the occupied blocks can be swept, the three free blocks will be
merged into one (much larger) free block. That would reduce free space
fragmentation.
