I know that we've had some serious issues with any Java 7 after update 25. They turned off a lot of network permissions and other things, as a security measure, that used to be available in versions prior to update 25. But that was when we were running CF Server 9.
Ever since we upgraded to CF Server 10 (making sure that we got the CF installer that came with Java 8), we've had very few issues relating to Java.
It seems odd, to me, that the host upgrading to 1.8 while your server is at 1.6 would cause any problems. It very well could be something else. I'd ask the host provider for documentation outlining exactly how/why their 1.8 could cause interference with your 1.6.
Updating ColdFusion fixed the issue. Thanks.
Glad to hear it! I wish more issues were so easily corrected with just a simple update. Amiright? And thank you for marking my answer as correct. I do appreciate it.
