Java malfunctioning

Heys, so basically, I have the following problem:
Either the client won't inject, or it won't connect. Both problems are the JAVA-based problems for which you need to update your java version, but I've already tried that a multitude of times and it still hasn't worked.

Does anyone have any suggestions on what to try next to fix this?

With JDK 7.0 (64-bit)

With 7.21 it doesn't work either
