Memory Leak in SSXA in Relation to Updates of Website Sections (Doc ID 1502365.1)

Symptoms

ISSUE 1:

The website has 4000+ nodes inside.  The corresponding objects in memory are about 50+MB.  After the update of a single node of the website structure (delete, move, change of CSP, insert) there are duplicates of the whole tree within the memory.  It is obvious that a change of one node of the tree is creating the whole tree from scratch.

ISSUE 2:

Old tree is not removed from memory.  There are various heap dumps to find out the root cause of the problem but it seems to be a problem with the standard implementation.

After several changes there is an OutOfMemory exception and there is a need to restart WLS.  Even after undeploying SSXA from WLS a lot of objects are still in memory, including the problematic SectionNodes.
