Java

From otaking wiki

Java is a programmering language from Sun Microsystems designed to run on set-top boxes and various small devices. However, due to Java being too slow and bloated, that plain failed miserably.

Repurposing the whole thing for writing desktop applications also largely failed, partially for the reasons mentioned and partially because the GUI toolkit, AWT, was a useless piece of crap. A second attempt at a GUI toolkit, called Swing, put another layer of crap on top of AWT, resulting in something equally useless but slower, uglier and more unreliable.

Reportedly Java now runs OK on a powerful server, assuming you don't need to run any other applications.
