Unsupported major.minor version 51.0 실행 에러가 발생하니다.

[쿰람돔람]

Exception in thread "main" java.lang.UnsupportedClassVersionError: com/sun/tools/attach/VirtualMachine : Unsupported major.minor version 51.0

이에러가 발생하면서 실행이 안됩니다.
open jdk 지원 안한다고해서 오라클 자바로 설치를 다하였고 javac java java-version으로 java가 정상 설치 된것을 확인 할 수 있었는데요..
/usr/local/ngrinder-core-3.0.3/run_agent.sh

실행 시 실행이 안됩니다. 도와주세요..

[junoyoon]

느낌에.. 자바 잘못 설치하신게 맞는것 같습니다.

set 하셔서 환경 변수 리스트와..

java -version 으로 현재 값을 포스팅 해주세요.

그외에도 몇가지 더 잘못되어 있는데요..

3.0.3 은 현재 저희가 지원하는 버전이 아닙니다.

어디서 사용하실려는지 알려주시면 저희가 프로젝트를 유지하는게 큰 도움이 됩니다.

IP6 쓰시나요?

/etc/host 변경하셔서..
ip-110-0-1-179 해당IP

를 직접 기재해 보세요.

[쿰람돔람]

vi /etc/hosts 이렇게 했는데요..
127.0.0.1  54.229.119.21

계속 위의 에러가 발생합니다.

[junoyoon]

ngrinder ipv6를 지원하지 않습니다.
ip6 엔트리를 모두 지우시고

자신의IP 호스트명

만 하나 추가하세요.
