Eclipse on Ubuntu when the project is launched

Question

recently I switched to Ubuntu and I have run into problems in running projects with Eclipse. I do not know what it is, but when I try to launch a project (the same project gave no problems on Windows or Mac OS) is already launched many times that the application does not respond and are unable to end the application (in fact I have to use the system monitor to kill these processes). How can I fix?

Update, warning:

** (java:27562): WARNING **: Couldn't register with accessibility bus: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

To develop Java on ubuntu, you should download the official oracle JDK and eclipse directly from the eclipse website. I've done this on many Ubuntu PCs and never have trouble this way. Using the ubuntu-packaged java and eclipse lead to trouble, though.
