Using a Log Server to Log a Java Stack

An el observer is a look up table of like user accounts, isn't it? In normal isr identification, in normal use, when not being abused. But on the un up dated version, you can just go to a web side and make that web sit contact an eld observer you control with a query you have written. And then it will assume the answer it gets back is a dot class file, and it will execute it in the jafo virtual machine. Oh jes yah. That is remote code execution, and its most bad.
