Eclipse's "unhandled event loop Exception" problem solving method

I've never had this problem before, and when we find that the system is self-loading, it starts to trigger the bug.

"Unhandled event Loop Exception" error occurred when clicking Open Java file or XML file from views such as Error-log, the error message is as follows:

My solution: find this after searching online.

Workaround: Reload the next JDK (without restarting the machine) or not. Then, modify the workspace, restart the machine, OK. Found that many problems can be solved by modifying workspace, suggest a project a workspace. The above method is invalid!! Google found it seems to be open. The default editor for Java has a problem with win7x64-bit notebooks, workaround: Help->install new software, from http://download.eclipse.org/windowbuilder/WB/release/R201309271200/4.3 download Windowbuilder, and set it as the default. Java Editor. There is no bug when switching back to the. java file after you restart Eclipse, but switching back to the. xml file will trigger the bug.

Finally, the ultimate solution:Update Win7! OK, problem solved!

(Windows Update the next win7, done!!) So: Go directly to Windows Update and install the patch on security! )
