If you are using Linux (Ubuntu and Debian in my case) and are being haunted by unresponsive, CPU and memory hogging Java applications you might find this piece of information useful:
- Check if you are using OpenJDK by issuing “java -version” in a terminal.
- If something with “OpenJDK” comes up, follow instructions (in german, but you get the point) on how to switch to the Java JDK from Oracle.
Netbeans now runs like a breeze now. Enjoy :)
