Redmine

Redmine no longer supports JRuby, and most of the code related to JRuby was removed in Redmine 4.1.0 (#29441). However, some code, test conditions, and comments that were written for JRuby still remain in the source. For example, config/configuration.yml.example still contains a note about "Windows + JRuby 1.6.2".

I would like to propose removing them. The attached patch removes the following:

• Code
  • Redmine::Platform.mswin?: the check for RUBY_PLATFORM 'java'
  • Redmine::Utils::Shell.shell_quote_command: the branch for JRuby on Windows that returns the command without quoting
  • Redmine::Scm::Adapters::AbstractAdapter#parse_xml: the workaround that removes the XML declaration on JRuby
  • extra/svn/reposman.rb: the check for RUBY_PLATFORM 'java' in mswin?
  • lib/tasks/ci.rake: the selection of the jdbcsqlite3 adapter
• Tests
  • test/test_helper.rb: the replacement of backslashes in repository_path, which was needed only for JRuby on Windows
  • test/unit/lib/redmine/scm/adapters/git_adapter_test.rb: the JRUBY_SKIP and JRUBY_SKIP_STR constants, the six branches that skip tests on JRuby, and the comment that explains why they were skipped
  • test/unit/repository_bazaar_test.rb: the JRuby condition in RUN_LATIN1_OUTPUT_TEST
  • test/unit/lib/redmine/export/pdf_test.rb: the selection of the "SJIS" encoding on JRuby
• Comments
  • config/configuration.yml.example: the note about paths that contain spaces on "Windows + JRuby 1.6.2". In addition, "On Windows + CRuby" is changed to "On Windows", because the distinction is no longer necessary.

The patch does not change the behavior on CRuby, because all the removed code was executed only on JRuby.
