I tried to paste some text into NetBeans. No text appeared. Possibly there was

I downloaded a Java upgrade (something number 9), after a message appeared by
the task bar. Sometime, the download finished, and I installed the upgrade.
I started Visual Studio 8.
I went back to NetBeans, and the window was blank. I clicked on the "Close"
button, but NetBeans did not respond.
I killed NetBeans using the Task Manager.
Please attach full thread dump and the log file so that we can diagnose what
