For anyone interested. The commit involves addressing two needs.
1) Enforcing MVEL reflection mode throughout - MVEL ASM optimiser can
NEVER be used for anything (it doesn?t add much value anyway).
2) Avoiding giving the template system the root class loader(which we use
for dynamic stuff), as those templates are statically cached.

The root of the perm gen leak has now be solved, thanks to some

work by community developer Davide Sottara.
This is just in time for the 5.6 release going out this week. You will
not need to use the kbase.dispose() work around.

Somewhere a ref is being held, that shouldn?t be - we just haven?t found
it yet.
