Description

Constant growth of memory using platform security 1.0.0 results in heap overflow as memory usage incerases with permission checks.

Having a look at it I found two problems, for which I can submit a patch:

• a value from m_permissions is never retrieved, as the PemissionsInfo Array is never equals to an existing key
  Solution: invoke get with an instance of Entry, change Entry.equals to check for deep equality of array-entries
• as the Persmissions instance kept as (non-weak) reference in the m_permissions values references the PermissionInfo[] key-entry, none of them can be garbage collected. As a result the size of m_permissions constantly grows
