With a fresh install of Jenkins 1.477, the following plugins are installed:
Static Analysis Utilities (1.43),
FindBugs Plug-in (4.42),
Warnings Plug-in (4.13),
Checkstyle Plug-in (3.29),
PMD Plug-in (3.29),
Task Scanner Plug-in (4.32),
Static Analysis Collector Plug-in (1.29).

In a maven job, a combined analysis is configured.
Then in the default graph configuration (job/test/analysis/configureDefaults/?), whatever values are written they are not saved when clicking the save button.
There is no error displayed in the browser or in the logs.
The lastModified time of the analysis.txt file in the job directory is changed when clicking the save button, but the content is always the same (500!200!50!30!PRIORITY!0).

Tested with both firefox and chrome.
