Yesterday, I installed Eclipse and NetBeans on my Linux Mint box (for those who don't know, they're IDE for programming in Java mainly). I did so with "apt-get install eclipse netbeans", just how you'd expect me to do.
Evidently, it installed a bunch of other stuff, such as Java's development kit (libraries and all that).
From then on, I've been having a strange problem, which is that all the buttons and menus have gotten a lot bigger in any Java application (that previously worked properly). I'm guessing this has to do with Java's virtual machine (since no code has been changed nor recompiled before or after the installation of the two softwares). I don't know much about Java quite frankly, and so I have very little clue as to how to solve this problem or what is causing this.
Basically, toolbars, buttons, spaces (between lines), stuff like that have all been amplified to the point where it's not even pretty anymore, and very impractical (because it takes so much space). Here are two screenshots, one of FrostWire (the fields at left are telling), and the second one is an interface used to connect to two chess servers (ICC and FICS). There again, the fields to be filled are way too big compared to what they're supposed to be.
