Eclipse Fails to Load (Exit Code 13) on fresh Fedora 22 w/ latest OpenJDK

Alright, before you chop off my head, I've spent the last two days poking around the internet trying to find a solution, and I'm at my wit's end. Additionally, I can't seem to login to askFedora, so here I am.

So, having installed Eclipse through the terminal via

sudo dnf install eclipse

trying to run it returns the following error:

JVM terminated. Exit code=13

I understand this to indicate there's a problem with the way I have eclipse.ini configured; specifically, what JVM I have it pointing to. whereis java returns /usr/bin/java, and in /etc/eclipse.ini I have the following two lines:

-vm
/usr/bin/java

java -version meanwhile returns

openjdk version "1.8.0_45"
OpenJDK Runtime Environment (build 1.8.0_45-b13)
OpenJDK Server VM (build 25.45-b02, mixed mode)

which, if I'm not mistaken, indicates that I have the latest OpenJDK Runtime Environment installed.

So, I'm stumped. Any ideas?

Solution

The problem - and the solution - are explained here:

Cannot run Eclipse; JVM terminated. Exit code=13

Please run whereis java and ls -l /usr/bin/java.
If you happen to have multiple JDKs, you should also consider alternatives. For example, run alternatives --display java.

Note

The -vm option and its value (the path) must be on separate lines.

Addendum

Make sure your JDK and Eclipse are either BOTH 32-bit, or BOTH 64-bit.

Here are the details from my system:

alternatives --display java

 java - status is auto.
 link currently points to /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.65-2.5.1.2.el7_0.x86_64/jre/bin/java
 ...

cd /opt/eclipse;file eclipse

eclipse: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.4.0, not stripped

cat cat eclipse.ini

At this point, I would strongly encourage you to either run eclipse-clean or (better!) delete and re-install Eclipse. Make no changes to the default eclipse.ini, until you get it working.
