All that this dialog shows is the command line options given to Eclipse, and therefore does not even hints to what went went wrong (which makes me wonder why Eclipse even bothers to show it). Look in the workspace/.metadata/.log file, the reason for the failure might be there (but check the date/times to be certain). If that doesn't work, open a command prompt, 'cd' to the Eclipse directory and run Eclipse from there; that should tell you more.
Recently I had installed 'Eclipse for Java EE Developers' in my laptop(I am using Windows XP). But when ever I run eclipse.exe, the eclipse workspace loading screen pops up and goes away immediately. I have also installed
(1) Java(TM) 6 update 14
(2) Java (TM) SE Development Kit 6 update 14
in my laptop. But no matter how many times I try, the workspace/ eclipse environment never get loaded.
I even tried by creating a new user and launching eclipse from there. But still it is not working. I was thinking that it may be because I am using Netbeans 9 that is causing this problem, so I had removed it, but still no use!
Look in the workspace/.metadata/.log file, that should give some hint as to what went wrong. If you you can't tell, post the file.
There is no NetBean/Eclipse connection - I run both without problems.
One more thought - JDK 6u14 is fairly old, I recommend updating to 6u21.
P.S. I recall asking you to start a new topic, yet you appended an unrelated question (you are not running Win 7 and you are not getting the error that the original poster indicated) to someone else's post again...
