 | 09.02.2020 Workaround | **pdd** fails to parse files in charsets other than UTF-8 with error `invalid byte sequence in UTF-8`. Workaround: exclude `src/test/wiremock` directory. Bug: [yegor256/pdd#143](https://github.com/yegor256/pdd/issues/143) Commits: [30aab7d](https://github.com/php-coder/mystamps/commit/30aab7dc8c265804efef382422e7cae9e53187f3), [ab563b6](https://github.com/php-coder/mystamps/commit/ab563b653279625120121babccdfd915181ee46d) |
 | 07.02.2020 Workaround | [php-coder/mystamps#1248](https://github.com/php-coder/mystamps/issues/1248): **wiremock** logs warnings for static resources when there is no stub mapping. Workaround: create mappings for such resources. Bug: [tomakehurst/wiremock#1247](https://github.com/tomakehurst/wiremock/issues/1247) Commits: [0018ad4](https://github.com/php-coder/mystamps/commit/0018ad44a21379b8179f94e954795c66b6d50bbc) |
 | 24.11.2019 Workaround | [php-coder/mystamps#1156](https://github.com/php-coder/mystamps/issues/1156) After updating **html5validator** to 0.3.2, the `--ignore-re` has stopped to work. Workaround: revert and pin the version to 0.3.1 Bug: [svenkreiss/html5validator#64](https://github.com/svenkreiss/html5validator/issues/64) Commits: [9a0d695](https://github.com/php-coder/mystamps/commit/9a0d695ccac1deeba0c4280779bbac11ebf3ac4d) |
+| 07.03.2020 Workaround | [php-coder/mystamps#1072](https://github.com/php-coder/mystamps/issues/1072): AJAX-related tests don't work in **htmlunit** and fail with `ReferenceError: "Headers" is not defined`. When the code got updated to use another version of constructor of `Headers` class, tests fail with error `ReferenceError: "fetch" is not defined` error. Bug: [HtmlUnit/htmlunit#78](https://github.com/HtmlUnit/htmlunit/issues/78) Workaround: because "the fetch api is not supported so far", let's use axios library instead. Commits: [f224e94](https://github.com/php-coder/mystamps/commit/f224e944b367036458ce9d7ce0c596504766ef8e) |
+| 07.03.2020 Workaround | [php-coder/mystamps#1072](https://github.com/php-coder/mystamps/issues/1072): `sendKeys()` method from **htmlunit** fails with `StringIndexOutOfBoundsException: start > length()` exception when we fill a field again. Bug: [HtmlUnit/htmlunit#142](https://github.com/HtmlUnit/htmlunit/issues/142) Workaround: open a page on every test to avoid a state from other tests.
