 This section is intended to contain the list of known issues that are not quick to solve i.e. those that occur in included libraries. If possible there is a workaround to the issue. This list does not replace the bugtracking tool for CzechIdM - https://redmine.czechidm.com
-  * Converter lib error - Sometimes the error `org.modelmapper.MappingException: ModelMapper mapping errors: Converter org.modelmapper.internal.converter.CollectionConverter@7214dbf8 failed to convert` occures. It is caused by the bug in the library "ModelMapper". Workaround is to restart the CzechIdM system. May be fixed in new version of ModelMapper - more info at https://github.com/modelmapper/modelmapper/commit/06dcce414ad56c6d200dda67fcd2670e9933c9ed

+==== Flyway ====
+To prevent application startup fails due to Flyway error, property ''-Djava.util.Arrays.useLegacyMergeSort=true'' has to be added into environment properties. If property is not set, then application can fail on error:
+<code>Error creating bean with name 'flywayCore' defined in class path resource [eu/bcvsolutions/idm/core/config/flyway/CoreFlywayConfig.class]:
+Initialization of bean failed; nested exception is java.lang.IllegalArgumentException: Comparison method violates its general contract!</code>
