But i am sure that i only installed jdk 1.7 on my Centos:

[root@localhost tryit]# rpm -qa |grep jdk
jdk-1.7.0_45-fcs.x86_64
[root@localhost tryit]# echo $JAVA_HOME
/usr/java/jdk1.7.0_45/
[root@localhost tryit]# java -version
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)
[root@localhost tryit]# javac -version
javac 1.7.0_45

The Weird thing is, when i tried to restart jira with "atlas-run".

First time, i met the error also,

But after a while, i successfully started jira with "atlas-run", i even do not know what i did, actually i did nothing but search about the error on web browser.

I suppose it is caused by following configuraion in pom.xml

<plugin>
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
            <source>1.6</source>
            <target>1.6</target>
        </configuration>
    </plugin>

I updated to be 1.7 now it is working.
