This maybe a question I need to ask on the Solr mailing list, but let me try here first.
Every now and then, I see the following error in solr.log file, any idea what maybe causing it (this is all that there is in the log):
INFO - 2016-03-24 11:05:30.130; [ ] org.eclipse.jetty.util.log.Log; Logging initialized @564ms INFO - 2016-03-24 11:05:30.382; [ ] org.eclipse.jetty.server.Server; jetty-9.2.10.v20150310 WARN - 2016-03-24 11:05:30.406; [ ] org.eclipse.jetty.server.handler.RequestLogHandler; !RequestLog INFO - 2016-03-24 11:05:30.410; [ ] org.eclipse.jetty.deploy.providers.ScanningAppProvider; Deployment monitor [file:/home/opuser/OP/OpenPages/OPSearch/solr/server/contexts/] at interval 0 WARN - 2016-03-24 11:05:30.483; [ ] org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration; Config error at <Set name="tempDirectory"><Property name="jetty.base" default="."/>/solr-webapp</Set> WARN - 2016-03-24 11:05:30.484; [ ] org.eclipse.jetty.deploy.DeploymentManager; Unable to reach node goal: started java.lang.NoSuchFieldException: TYPE at java.lang.Class.getFieldImpl(Native Method) at java.lang.Class.getField(Class.java:1101) at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration.set(XmlConfiguration.java:490) .... .... ....

From here on, I cannot access the Jetty server.
I'm using Jetty that comes with Solr 5.2 and the above error is reported when I try to start Solr from the command line using: bin/solr start -p 8983 -m 4098m -s ../solr_index. My environment is Linux.
To "fix" the issue, I issue Solr's "stop" command followed with the "start" again and now everything works.
Thanks in advanced
