JAVA update 1.8.0_242 breaks SnapCenter Plug-in Loader service for Linux

[Hans088]

After updating our CentOS servers the SnapCenter Plug-in Loader service (spl daemon) could no longer be contacted on port 8145. After running some tests it seems that the daemon is not compatible with Java svm 1.8.0_242, the deamon does not start a listening port on tcp/8145 so there is no communication possible with the SnapCenter server and backups stop working. No errors are being logged locally, the only thing noticable in spl_init.log is that Jetty cannot be initialized properly - Logging initialized @-1ms to org.eclipse.jetty.util.log.Slf4jLog. After downgrading to jvm 1.8.0_232 everything starts working again, until the next update cycle ofcourse. These problems are reproducible with plugin versions 4.2 and 4.3.

Anyone else experiencing this and/or has a workaround for this issue?

Hi,

I see this issue/symptom documented in KB:1103592

Symptoms: 'netstat -an |grep 8145' shows no process listening on port 8145

Java version 1.8.0_242 is not compatible yet for SC 4.x,  downgrade to a previous version of Java. Both 1.8.0_232 and 1.8.0_222 are known to work.

SnapCenter for Oracle stops working after upgrading Java to 1.8.0_242:

Thanks!

Thank you! Somehow I missed this KB article. To clarify for others: this is not only an issue with the Oracle plugin, but also for other plugins running on Linux (in my case, MySQL).
