Exception message (when using Fuzzy C-means tool)

[Otsoa]

Dear all,

I was trying to use this Fuzzy C-means application (which is a part of the Toolkit). An Exception pop-up appeared, stating:

(Fiji Is Just) ImageJ 2.0.0-rc-30/1.49u; Java 1.6.0_24 [32-bit]; Windows 7 6.1; 220MB of 1226MB (18%)
 
java.lang.UnsupportedClassVersionError: net/sf/ij_plugins/clustering/KMeansClusteringPlugin : Unsupported major.minor version 51.0
 
This plugin requires Java 1.7 or later.


I have installed the newest version (Java 8.0 I think). Is it so that I need to unistal the Java 8 version and download version 1.7?

Cheers! :)

Hi Otso,

>I have installed the newest version (Java 8.0 I think)

>(Fiji Is Just) ImageJ 2.0.0-rc-30/1.49u; Java 1.6.0_24 [32-bit]

It looks like although you may have Java 8 installed on your system, ImageJ
is using Java 6 (The "All Platforms (No JRE)" downloads[1] will use your
installed Java by default. Other downloads will use a bundled Java 6).

You can change the version of Java being used by following the instructions
in this FAQ entry[2]. You can also manually verify the Java version used by
clicking on the ImageJ status bar[3].

Hopefully this process will be much simpler and more flexible soon as
ImageJ moves to Java 8[4].

Let us know if you run into any more problems.
