Why I cant't import ComponentAccessor in behavior ?

[daymonTwo]

Always when I try import 

import com.atlassian.jira.component.ComponentAccessor

while creating behavior i get error 

unable to resolve class com.atlassian.jira.component.ComponentAccessor @ line 3, column 1. import com.atlassian.jira.component.ComponentAccessor; ^ 1 error

Please, tell me what I doing wrong? 

version jira 5.0.3 

Thanks.

Good question. I cannot reproduce your problem.

Are you really still using Jira 5.0.3, or is that the scriptrunner version?

If it is your Jira version, then I'd upgrade the system. It might be that the class is not available in that version.

I have tested the import on Jira 7.7.1 (SR 5.6.12) and Jira 8.5.0 (SR 5.6.14.1-p5) and both work.
