Issue
We are doing a performance analysis using Java Mission Control and while checking the errors tab we see a lot of exceptions coming from freemarker.core.FMParser$LookaheadSuccess class
Environment
Liferay DXP 7.3
Resolution
If those errors only arise while doing a recording with JMC and doesn't get reflected in the logs, they can be ignored as a false positive.
LookAheadSuccess extends Error and an instance of LookAheadSuccess is created when you create a new instance of FMParser that's why JMC logs it as error despite not being thrown.
