Start the project in eclipse for a while, or sometimes directly in the startup times Ioconsole Updater's fault. Checked online, this is an eclipse bug, and the list sees bug 176508,bug 198188,bug 243877. I am happy to see in bug 243877 that the bug was built from 2008-08-12 until today, and there are still people who spit in the list.
The online approach is:
Enter Window–>preferences–>run/debug–>console to remove the check for the fixed width console in the Debug Console settings.
In fact, doing so often does not work.
This bug reproduce is also very simple, is the console constantly output information, after a period of time, reported this error. The reason for personal understanding is that the console output is too much information, although it does not affect debug, but the pop-up dialog box is still very uncomfortable.
The temporary solution is to manually clear the console periodically after removing the check box for the fixed width console.
