I installed Eclipse PDT (Eclipse for PHP projects) and I tried to open a file with embedded applet. Eclipse crashed right away. After the crash, there was no way for me to start Eclipse again. After some searches, I stumbled upon this blog. I deleted the content of the .settings directory as explained in the blog, but Eclipse still failed to start. Then  Jason told me to remove user properties files. They could be found on the directory .metadata. This directory itself was located in the workspace directory. After I did that, Eclipse started, but I lost all of my workbench configurations and I had to redo all of the config. But it was better than not having Eclipse start at all. At least I learnt something new.
