When i try to start my jenkins slave, the slave exists with error:

Is there anyway to fix this? I've googled, and googled, and googled, but can't find anything to solve this problem.
Answer
I haven't faced the same issue, but I guess it may be linked to this: https://issues.jenkins-ci.org/browse/JENKINS-27624
(It is in case your Jenkins version is 2.54 - minimum java version should be 8)
