[jira] [Updated] (GROOVY-9637) Improve the performance of GString

["Daniel Sun (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/GROOVY-9637?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Daniel Sun updated GROOVY-9637:
-------------------------------
    Description: 
{{GString}} will run {{toString()}} whenever its implementation needs its literal string, but unfortunately its literal string will be re-constructed for each time and the process costs quite a little of time.

So I propose to check whether {{GString}} values are all of immutable type, e.g. primitive types and their boxed type, {{String}}, etc. If yes,  use the cached literal string, otherwise re-construct the literal string.
