Been a Java developer since 1999 and have used everything, MS Visual J++, JBuilder, NetBeans, Eclipse, IntelliJ. Sadly I just got the "joke" :( Never put two and two together, I just thought it was a cool name...
What happened to JBuilder? I had used for a while earlier. Seemed good then. (ex-Borland fan here.) Did it get messed up in the general mess up that Borland (aka a few other corp names over the years) did to their once-good products, or was it some other reason?
