Thanks for the heads up about the missed entries. We’ll get those added when possible.
I’m not familiar with the log you’ve posted. It looks like some sort of internal debug log, where Java appears to be attempting to call Java methods (bits of code) but cannot locate them. I would assume a partially installed JRE would cause this issue.
My best recommendation would be to try a heuristic powered uninstalled app: Revo Uninstaller would be the most obvious choice.
