You are now the second person to report a problem with Java on Linux. Are you sure the Java version is 1.8? I cannot find any such version. I've searched the Oracle site and cannot find mention of Java 1.8 or Java 8.

In terminal type % java -version
Do you get an error?

It is my guess the problem is 64-bit Java, similar to Windows. The answer for Windows is to install the 32-bit Java last. How do I download and install 32-bit Java for Linux? The 32-bit version will have linux-i586 as a part of its name.

I am not a Linux user so cannot test things. If still problems, find the Limewire program package and find LimeWire.jar and execute this instead. It will probably be found within a LimeWire sub-folder called either java or lib.

It would be a huge kudos if any Linux users out there could give a help in hand here.
