Ethan Li created SOLR-12525:
-------------------------------

             Summary: Solr 5.3 and JDK10 compatibility investigation
                 Key: SOLR-12525
                 URL: https://issues.apache.org/jira/browse/SOLR-12525
             Project: Solr
          Issue Type: Improvement
      Security Level: Public (Default Security Level. Issues are Public)
          Components: SolrJ
    Affects Versions: 5.3.1
            Reporter: Ethan Li


We are trying to use JDK10 to run Solr 5.3.1 and we are facing some problems:

We removed the following JAVA options in solr.in.sh as what SOLR suggest because it wont start:

UseConcMarkSweepGC
 UseParNewGC
 PrintHeapAtGC
 PrintGCDateStamps
 PrintGCTimeStamps
 PrintTenuringDistribution
 PrintGCApplicationStoppedTime

And the options left in solr.in.sh:
 # Enable verbose GC logging
 GC_LOG_OPTS="-verbose:gc -XX:+PrintGCDetails"

 # These GC settings have shown to work well for a number of common Solr workloads
 GC_TUNE="-XX:NewRatio=3 \
 -XX:SurvivorRatio=4 \
 -XX:TargetSurvivorRatio=90 \
 -XX:MaxTenuringThreshold=8 \
 -XX:ConcGCThreads=4 -XX:ParallelGCThreads=4 \
 -XX:+CMSScavengeBeforeRemark \
 -XX:PretenureSizeThreshold=64m \
 -XX:+UseCMSInitiatingOccupancyOnly \
 -XX:CMSInitiatingOccupancyFraction=50 \
 -XX:CMSMaxAbortablePrecleanTime=6000 \
 -XX:+CMSParallelRemarkEnabled \
 -XX:+ParallelRefProcEnabled"

After that SOLR runs but it got an error:

[0.001s][warning][gc] -Xloggc is deprecated. Will use -Xlog:gc:/solr/logs/solr_gc.log instead.
 [0.001s][warning][gc] -XX:+PrintGCDetails is deprecated. Will use -Xlog:gc* instead.

ERROR: Failed to get system information from [http://localhost:8983/solr] due to: java.lang.NullPointerException

 

The exception behind from the log:
 2018-06-27 20:00:55.411 INFO (main) [ ] o.e.j.s.Server Started @1849ms
 2018-06-27 20:01:20.192 WARN (qtp1646371921-17) [ ] o.a.s.h.a.SystemInfoHandler Error getting

Removing JMX related option (or disable) won't fix this.

Please advise.
