For anyone interested. The commit involves addressing two needs.<br>
1) Enforcing MVEL reflection mode throughout - MVEL ASM optimiser can NEVER
be used for anything (it doesn’t add much value anyway).<br>
2) Avoiding giving the template system the root class loader(which we use
for dynamic stuff), as those templates are statically cached.</font></tt><font size="3" color="blue"><u><br>

This is because the JCR2GIT migration tool, in 5.6 is needed for our 6.0
product. <br>
