I don’t know about you, but I love the Firefox’s undo-close-tab feature (Ctrl+Shift+T). If you use Eclipse you might be glad to know you can undo the close-tab action in Eclipse as well. You can do that both using your mouse by clicking on the yellow left arrow you can see in the Eclipse toolbar and through the keybord using the Alt+Left Arrow key combination.
I hope this helps.
It might happen that while running a Java application within the Eclipse environment you get an OutOfMemoryError due to the maximum amount of memory dedicated to the heap. You can fix it by increasing the minimum (-Xms parameter) and maximum (-Xmx parameter) heap size. You can do it in two different ways:
1. By editing your eclipse.ini file you find under your Eclipse installation directory. Within that file you should find two lines similar to the following ones:
-Xms40m
-Xmx512m
You might want to change them depending on your hardware. For example I changed them as follows:
-Xms256m
-Xmx1024m
It means: “start with an initial heap size of 256 MB and grow to a maximum of 1024MB, that is 1GB.”
2. By editing the Run Configurations in Eclipse. To do this, right-click on the class you want to run (the one with the main method) and then select:
Run As -> Run Configurations
Click on the Arguments tab. In the VM Arguments box type:
-Xms256m -Xmx1024m
or whatever you prefer, depending on the hardware you possess.
IMPORTANT NOTE: It is strongly recommended that you make a backup copy of your eclipse.ini file before editing it in any way.
