Issue with Java version in linux.sh execution?

I have a .sh file as shown below.

export JAVA_HOME=/usr/jdk/latest
export PATH=$JAVA_HOME/bin:$PATH
java -Dlogback.configurationFile=./conf/logback.xml  -cp CLASSPATH:Client.jar com.test.main.Client 
exit

      

        
        
        
      

    

If i run the script i get below error message.

Exception in thread "main" java.lang.UnsupportedClassVersionError: com/test/main/Client : Unsupported major.minor version 52.0

      

        
        
        
      

    

I read some doc and their story because of a problem with the java version this is happening. I am checking my local machine version and Linux server version. Both are the same. I am using gradle 2.4 to build my application and set sourceCompatibility and targetCompatibility to 1.8.

sourceCompatibility = 1.8
targetCompatibility = 1.8

      

        
        
        
      

    

Local Java version.

java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b15)
Java HotSpot(TM) Client VM (build 25.45-b02, mixed mode)

      

        
        
        
      

    

Linux server Java version

java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)

      

        
        
        
      

    

If I just edit the .sh file (add a space) and run it works fine.

Could you please help someone to solve this problem?
