Conspiracy to distribute a schedule 3 is breaking the law but it is not up there with dealing heroin. Plead out with no jail time would have a minimal impact on many people. But it went down as a felony.
A felony is going to hit harder in some professions. For example law, medicine, and IT. Reason for IT sensitivity is that you have assess to data. And you could wreak havoc.
If they ask you need to tell them. Even if they don't ask maybe you should tell them. A friend of mine had a DUI and the new employer did not ask but when they tried to put her on the insurance policy the DUI came up and she was dismissed.
Look for stuff that stays away from enterprise data as that is going to be very protected.
Not really Java but games. But working in games is brutal. Look for stand alone apps.
Not something to put on the resume but during the interview process you might ask about hiring polices and background checks under the guise of how long does it take. Requiters talk to each other and you don't want to get flagged as a felon. Give yourself a chance to get out without showing your hand. I don't really know what the right answer is here. Just trying to give you some ideas.
