No, it seemed to have wiped out my J2EE library listing under the Preferences – MyEclipse – J2EE – Library Sets – J2EE 1.3.
Also, I had previously added a new SDK under the Preferences – Java – JRE section that was also removed.
It took me a while but I finally figured out where the J2EE .jar files were located under the MyEclipse directory so I am up and running again, I just thought that this was VERY strange behavior since I SWEAR that I didn’t do anything that would have removed any of the above.
