Problem with Java 1.8 and SSL

I am using Elluminate Live 10! which is an old application and I have no more support. Using Java 1.7.51 everything still works (I had to do some small manipulation but everything works). I tried under Java 1.8 to access to my application (which is a JNLP) and I get an error message.

I have a master server which talk with a slave server using JINXSSL. and the problem seems to be between those two.

I don'T play so much on those server so I don't know much.

But there is definetly something in Java 8 that block my app. Can someone be kind enough to help me? Is there any change that could have lead to this problem?

Thanks

Jon
