Update priority field if user does not have a permission "Assign issues"

[zaharovvv_suek_ru]

We are using ScriptRunner.
We are changing a priority field in Custom Listener when an event `Issue updated` is happened.
This code updates a `priority` field of issue if user has permission "Assign issues" in Issue Permissions tab of my project.
However, if user does not have permission "Assign issues" in Issue Permissions tab of my project, then this code is not updating priority field.
What can I do to update priority field if user does not have a permission "Assign issues", but user has a permission to "Edit Issues"?
In my view, it should be enough to have a permission "Edit Issues" to be eligible to edit priority field. Is it correct?

I suggest using IssueManager to update issues instead of IssueService. 

Like so:

import com.atlassian.jira.event.type.EventDispatchOption
import com.atlassian.jira.component.ComponentAccessor

issue.setPriority(priority)
def user = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()
ComponentAccessor.getIssueManager().updateIssue(user, issue, EventDispatchOption.ISSUE_UPDATED, false)

@Ivan Tovbin Thanks for your answer. I've tried to use your code, but the following code is outlined by red color:

issue.setPriority(priority)
ComponentAccessor.getIssueManager().updateIssue(user, issue, EventDispatchOption.ISSUE_UPDATED, false)

The error says:

1. Cannot find matching method "setPriority"

2. Cannot find matching method "updateIssue"

Can you show me the code as it looks like on your end?

So the final code should look like this:

import com.atlassian.crowd.embedded.api.User
import com.atlassian.jira.bc.issue.search.SearchService
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.IssueManager
import com.atlassian.jira.web.bean.PagerFilter
import org.apache.log4j.Logger
import com.atlassian.jira.issue.ModifiedValue
import com.atlassian.jira.issue.util.DefaultIssueChangeHolder
import com.atlassian.jira.ComponentManager
import com.atlassian.jira.issue.index.IssueIndexingService
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.util.ImportUtils
import org.apache.log4j.Category
import java.sql.Timestamp
import com.atlassian.jira.event.type.EventDispatchOption;

def log = Logger.getLogger("com.acme.CreateSubtask")
IssueManager issueManager = ComponentAccessor.getIssueManager()

def issue = issueManager.getIssueObject("Bar-1")

def customFieldManager = ComponentAccessor.getCustomFieldManager()


def environmentValue = issue.getEnvironment();
log.info('environmentValue ' + environmentValue)
issue.setEnvironment('New Environment 1')


def user = ComponentAccessor.getJiraAuthenticationContext()
    .getLoggedInUser()
log.info('user ' + user)
issueManager.updateIssue(user, issue, EventDispatchOption.DO_NOT_DISPATCH
    , false)
