Java vs Iced tea

Anyone else having this issue?Iced tea appears to be ****-has never worked.Even after the clusterflock of codecs/multimedia, etc.I've never had the fake java work on my platform.Why can't we just unistall tea and use linux based java?If I do that will it destroy my install?I DO know the us.gov site has not been compatible since java 7.xx:beat-up:
Here's the error output from iced tea:
