hs_err_pid followed by four numbers has appeared twice on my desktop. I Googled this, and the consensus seems to be that this is a Java error, and that I should uninstall the Java on my computer and install the latest version. (I keep getting notices that a new Java version is available.) Currently on my computer under Add/Remove are Java (TM) 6 Update 29, Update 3, and Update 7. Before I do this (if this is the correct thing to do), can someone tell me why I need Java? I went to the Java article on Wikipedia, and it's all Greek to me. If I uninstall Java and don't install the new version, what will happen to me?
