Category

This change is exactly one of the following (please change [ ] to [x]) to indicate which:

• [x] a bug fix (Fix #1975)
• [ ] a new Ripper
• [ ] a refactoring
• [ ] a style change/fix
• [ ] a new feature

Description

I simply changed the behavior to close the dialog instead of terminating the application itself.

Technically, mvn test failed.

Boot Manifest-JAR contains absolute paths in classpath 'X:\WORKING\DIRECTORY\target\test-classes' Hint: -Djdk.net.URLClassPath.disableClassPathURLCheck=true

But it doesn't seem relevant to my changes and did fail with the HEAD version, too.

Testing

Required verification:

• [ ] I've verified that there are no regressions in mvn test (there are no new failures or errors).
• [x] I've verified that this change works as intended.
  • [x] Downloads all relevant content.
  • [x] Downloads content from multiple pages (as necessary or appropriate).
  • [x] Saves content at reasonable file names (e.g. page titles or content IDs) to help easily browse downloaded content.
• [x] I've verified that this change did not break existing functionality (especially in the Ripper I modified).

Optional but recommended:

• [ ] I've added a unit test to cover my change.
