Issue Summary

The /jql/parse REST API endpoint does not work if a third-party app adds a JQL alias that matches an existing field name. ScriptRunner for example adds a property called scriptrunner.issuelinks which has the alias issueLinkType. Note that there is an also a native JQL alias with the same issueLinkType name.

As a consequence, JQL of the type issueLinkType = LINK_TYPE cannot be parsed anymore by apps.

Steps to Reproduce

1. Install ScriptRunner

1. Use the jql/parse REST API to parse the JQL query issueLinkType = Duplicate

Expected Results

The parsed field name should have been issueLinkType, as it appears in the input query.

Actual Results

The parser returns the field name issue.property[scriptrunner.issuelinks].types for the query. 

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
