Script "run_example.sh" not working.

[felipelageduarte]

I just grab the source code from git repository. I tried to run the script and got the following error

~/hist4j$ ./run_example.sh
Buildfile: /home/felipelageduarte/hist4j/build.xml

prepare:
[delete] Deleting directory /home/felipelageduarte/hist4j/output
[mkdir] Created dir: /home/felipelageduarte/hist4j/output

Could not find the main class: Hist4jExample. Program will exit.

Could anyone please help me and fix the script?

After a quick google search, this seems to be related to the version of the JVM you have installed. The recommended fix is to install the latest JVM.
