Problem/Bug Fixing Java 8 and MCPC+ for 1.5.2 ?

Specifically .... "This server is running CraftBukkit version git-MCPC-Plus-jenkins-MCPC-Plus-Legacy-653 (MC: 1.5.2) (Implementing API version 1.5.2-R1.1-SNAPSHOT)"

Although MCPC+ works okay with Java 7, it does not work correctly with Java 8. No plugins will load.


Typical plugin load failure:

Code:

[......etc......]

Why does this matter? Well, FTB Unleashed, a MC 1.5.2 modpack, does in fact run properly with Java 8.

And this newfangled FTB / Curse launcher always launches Unleashed games with Java 8. Okay....



Well it appears a server running MCPC+ and Java 7 cannot have clients join that are running Java 8. Something called "BouncyCastle" blows up which appears to be some encryption library that is not compatible between Java 7 and Java 8.

So everyone trying to connect to an Unleashed server running Java 7 and MCPC+ times out when the bouncycastle blows up.

If Java 8 is used on the server side with MCPC+, the connection error goes away, but now the public server is all screwed up because no plugins can load.

Is there any solution to making Java 8 work with MCPC+ and plugins?



And YES, MCPC+ for 1.5.2 is soooo dead. There's really no hope whatsoever that this might get fixed. But I thought I'd at least try asking.
