[jboss-jira] [JBoss JIRA] (WFCORE-4115) JDK11 - GC logging format needs to be reviewed

James Perkins commented on WFCORE-4115:
---------------------------------------
I do believe Java 9+ defaults to G1GC, however the format difference is because of [JEP
271|http://openjdk.java.net/jeps/271]. That JEP reimplemented GC logging which leads to
the new format. In the "Non Goals" it states:

Non-Goals
It is not a goal to ensure that current GC log parsers work without change on the new GC
logs.
Not all log entries will necessarily be reproduced in the new logging format.

Essentially there's nothing we can do. We'll have to use a new parser.
JDK11 - GC logging format needs to be reviewed
----------------------------------------------
Key: WFCORE-4115
URL: https://issues.jboss.org/browse/WFCORE-4115
Project: WildFly Core
Issue Type: Bug
Components: Scripts, Server
Reporter: Marek Kopecký
Assignee: James Perkins
Priority: Major
Labels: Java11, jdk11
Attachments: java-11-gc.log, java-8-gc.log
* Weird naming of gc log files
** I test this with JDK11
** I start standalone and stop standalone
** JDK10 creates JBOSS_HOME/standalone/log/gc.log (with detailed information) and
JBOSS_HOME/standalone/log/gc.log.0 (with brief summary of gc logging)
** I start standalone and stop standalone again
** JDK10 moves original gc.log to gc.log.1
** JDK10 keep original gc.log.0
** JDK10 creates new gc.log (with detailed information) and gc.log.2 (with brief summary
of gc logging)
** Can this be changed by GC settings?
* GC logs are much more verbose against jdk8 gc logs. Can this be fixed by some JDK10 gc
settings?
This is follow up for WFCORE-3996
