[MC-76544] minecraft 8.1 not working

A week ago i updated my java to java 8 and upon restart i got an error when tried to enter minecraft. I uninstalled and went back to java 7 but the problem remained. I have already made sure my graphic drivers were up to date and when i mentioned this to the help people on the forum they stopped helping and cut off contact. please help me resolve this issue because i cannot play on the realm that i pay for. this was the error.
