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

Aaron Ogburn commented on WFCORE-4115:
--------------------------------------
Thanks, [~jamezp]. So java 11 is defaulting to G1 and Java 8 defaults to parallel
throughput collector here so that's a notable difference. Parallel GC on java 8
produces 1 log line per GC. G1 produces multiline entries for each GC. So if you used G1
on java 8 also and compared, you'd probably see more similar verbosity from multiline
entires. I'm not aware of anything to scale back G1 verbosity on java 8 or 11.
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
