And this window appear: !Start_without_clean.png|thumbnail! There is easy workaround but user won't start Devstudio with -clean and many of them could be upset. Please see the log: [^rh-eclipse46-devstudio10.4-0.20170320.0955.el7.log.Without_clean_test_strict.txt] There is what I got when I installed FindBugs. I put some comments there so you can find sections installation/start without clean/start with clean. CC: [~psrna] [~vkadlcik]
