Hi Atlassian,
I have noticed in catalina.out a flood of errors like these
Error getting plugins
java.lang.IllegalStateException: Multiple plugins with the same key and version:com.atlassian.jira.ext.charting 2

Likely this is thrown when an error 500 occurs but this is not the problem. The problem is that ExtendedSystemInfoUtilsImpl.getPlugins() throws an IllegalStateException when run on JDK 1.7.0_13 but not on JDK 1.6.0_39. Since we need to switch to JDK 1.7 this bug has very high priority for us to be fixed.
The problem likely lies in the different behaviour of JRE 6 and 7 when adding elements to an empty TreeSet. The problem can be reproduced with the following code in the Groovy Script Runner
import com.atlassian.jira.util.system.ExtendedSystemInfoUtils import com.atlassian.jira.util.system.ExtendedSystemInfoUtilsImpl; import com.atlassian.jira.web.bean.I18nBean import com.atlassian.plugin.Plugin ExtendedSystemInfoUtils extendedSystemInfoUtils = new ExtendedSystemInfoUtilsImpl(new I18nBean(Locale.ENGLISH)); Collection<Plugin> plugins = extendedSystemInfoUtils.getPlugins()
I'm not sure if this behaviour came with JDK 1.7.0_13 or has been in JDK 1.7 since the beginning.
Regards,
Dieter
Workaround
Move JIRA over to Java 6. Please note as per our Supported Platforms Java 6 is not supported in JIRA 6.
- Install Java 6 JRE/JDK.
- Stop JIRA.
- Change the $JAVA_HOME to point to the Java 6 JRE/JDK.
- Clear our the plugin cache, as it is Java version dependent (starting up will cause failures if we don't clear it). To do so, remove the following directories:
$JIRA_HOME/plugins/.bundled_plugins $JIRA_HOME/plugins/.osgi_plugins
These are temporary files and folders and will be recreated when JIRA starts. - Start JIRA.
- Test you can create a Support Email.
