[jira] [Comment Edited] (CAMEL-16128) Camel cron expression parse
failure
[ https://issues.apache.org/jira/browse/CAMEL-16128?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17276983#comment-17276983 ]

--------------------------------------------------------------
That is because you are using spring as cron implementation and it seems to not support 7, if you use quartz then it can do 7 and more advanced cron expressions
However the 7 digit is year which is seldom in use.

> Issue Type: Bug
> Affects Versions: 3.5.0, 3.7.1
> Reporter: Adam Ostrožlík
> Priority: Major

> spring-boot camel-cron-starter + endpointdsl throws exception while using this expression:
>
> {code:java}
> 0 0 0 1/1 * ? *
> {code}
> Doc says that supported field count is 7. [https://camel.apache.org/components/latest/cron-component.html]
> Workaround is probably to omit last optional year character.
> Code causing this:
> {code:java}
> from(cron("cleanup").schedule("0 0 0 1/1 * ? *)){code}
> {code:java}
