Recently I've discovered another nice feature of Eclipse: you may paste a stack trace into the Java Stack Trace Console and use that nice hyperlinks to navigate the trace. You can open a new console instance from the Open Console drop-down menu in the Console view or even use an existing Java console. With Java Stack Trace Console it is possible to format the stack trace with standard Format key binding. If you use a running Java console, the pasted trace is presented in green color.
Nice feature for rapid analyzing of plain-text logs, isn't it?
P.S. This feature was introduced in Eclipse 3.1. Well, one has to pay more attention to "New and Noteworthy" issues ;)
