One of our customer has their own setting in java.policy file on Domino 11.0.1 environment.
After installed Domino 11.0.1 FP4 on this server, he found the existing java.policy file was overwritten by Domino 11.0.1 FP4 installer. This customer has to add their own setting again to java.policy file provided by FP4.
Compared with the java.policy file provided by Domino 11.0.1 and previous Fix Pack, the content of the new java.policy provided by FP4 has to change at all.
Because java.policy file can be customized by customer, this customer wish HCL don't update java.policy file if it is not changed at all in future Domino Fix Pack Installer.
