1.52.0

fix issue 406 : Slow GUI with JBoss EAP 6.2 (only since 6.2)
fix issue 415 : Periodic stack trace in Tomcat 8 logs 'java.lang.IllegalStateException: The resources may not be accessed if they are not currently started'
fix issue 423 : Link to DataSource Reference Returns HTTP 404
fix in the Liferay plugin, the monitoring page works after deploy, but is not found (404) after restart of Liferay (commit 78618d3). This was caused by interaction between web-fragment.xml and Tomcat 7 inside Liferay.
fix issue 377 : in JIRA, Confluence: Incorrect Installation Instructions on Atlassian Marketplace
improved: reduce the number of RRD files created in some conditions, by not creating a RRD file of mean times if a request is called only once (revision 3836). Otherwise, obsolete RRD files are automatically deleted after 3 months like before.
added: links "View in a new page" below the tables of threads and of current requests (revision 3839). For example when the app is under load, the new pages make it easy to refresh at will the details of threads or of the current requests to see if states change or not, without refreshing all the main page.
added: logout action in the menu on the right of the main report, if there is a http session (revision 3859)
In the Jenkins monitoring plugin, upgraded mininum Jenkins version to 1.509.3
added: In the Jenkins monitoring plugin, display of build steps and their durations, in the detail of each build statistics in the "/monitoring/nodes" page. See Example

fix "ORA-00911: invalid character", when using the sql-transform-pattern parameter, for the display of the explain plan of some sql requests (Oracle database only, revision 3799)
Drop Java 5 support. Said otherwise, a JDK or a JRE v1.6 or later is needed for javamelody v1.51 or later. For Java 5, previous versions of javamelody can still be used. (revision 3795)
Optimized desktop UI startup time, by downloading desktop app and caching locally (revision 3762)
improved: abstract very long sql requests ( issue 403 )
improved: in a graph detail, a checkbox can now hide maximum values in the graph, so that average values are better displayed when much lower than the maximum ( issue 368 )
added: PID in the heap dump file name (revision 3773)
