Signed-off-by: dependabot[bot] <support@dependabot.com> * Bump checkstyle from 8.15 to 8.16 (#4562) Bumps [checkstyle](https://github.com/checkstyle/checkstyle) from 8.15 to 8.16. - [Release notes](https://github.com/checkstyle/checkstyle/releases) - [Commits](checkstyle/checkstyle@checkstyle-8.15...checkstyle-8.16) Signed-off-by: dependabot[bot] <support@dependabot.com> * Do not extract file ending from Urls (#4547) * Fixes #4544 Do not extract file ending from Urls * Add tests * file type for any resource type * Keep simple file name extraction for files * checkstyle * Converts integrity check dialog to JavaFX (#4559) * Converts integrity check dialog to JavaFX Moreover: - Show entry by reference and not by id. Fixes #2181. - Fixes a few issues that occurred when opening the entry editor by code from the integrity dialog - Reuse gridpane in entry editor (should have a slightly superior performance) - Improve display of progress dialog - Invoke copy files task using central task executor * fix l10n fix aborting of copy files task and showing of integrity check dialog * fix l10n * Add uncaught exception message (#4565) * Add error message for uncaught exceptions Added a new view to the project. It's shown after the uncaught exception is logged. * Add simple text to fallback error view Added a label asking the user to look into the logfiles for more details. * Add error message to language files Added the error message to the german and english language files. * Add ErrorDialogAndWait Removed the FallbackErrorView. Added the showErrorDialogAndWait call instead. * BibTex parser triggered on focus out of the text area instead of on value change event * BibTex parser triggered on focus out of the text area instead of on value change event * Added a post-parsing validation to be sure there's no relevant unconsidered content into epilog. Added DialogService in SourceTab as current NotificationPane seems not working. * Added a post-parsing validation to be sure there's no relevant unconsidered content into epilog. Added DialogService in SourceTab as current NotificationPane seems not working. * Codacy/PR Quality Review change. * Codacy/PR Quality Review change.
