start C++ server in linux?? it report "Failed to initialize JVM" error

[smile]

Hi, all
     when I used jdk1.7.0 buiding ignite core?? and building C++ server in 
linux(Center OS) , when I start C++ server?? it report error as follow:


    ~/apache-ignite-1.7.0-src/modules/platforms/cpp/ignite]$ ./ignite 
   ERROR: Failed to initialize JVM 
[errCls=java.lang.UnsupportedClassVersionError, 
errMsg=org/apache/ignite/internal/processors/platform/utils/PlatformUtils : 
Unsupported major.minor version 51.0]


    And I have search this problem in google, which replies that because the 
JVM version is lesser than the jar??however, build ignite must be jdk1.7.0 or 
greater;


    how can I solve it ?


    Thank you very much !
