Application startup fails due to Flyway bug
100%
Description
Affected version: 7.8.3 when updated from 7.8.2
Tomcat server fails to start with the following exception:
org.springframework.beans.factory.BeanCreationException: 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!
As Ondra advised, this is probably a bug in Flyway and can be resolved by adding -Djava.util.Arrays.useLegacyMergeSort=true to JAVA_OPTS.
If there is no other solution, please add this information to the release notes for 7.8.3 and to the guide for installation CzechIdM.

This happened on the following environment:
OS: Fedora release 26 (Twenty Six)
Tomcat: apache-tomcat-8.5.27
Java: OpenJDK Runtime Environment (build 1.8.0_161-b14)
IdM was installed according to our standard tutorial: https://wiki.czechidm.com/tutorial/adm/czechidm_installation

The same behaviour for Windows when upgraded from 7.8.1 to 7.8.3.
Java version: Oracle JDK 1.8.0_152
Resolved by adding -Djava.util.Arrays.useLegacyMergeSort=true to Tomcat configuration (C:\Program Files\Apache Software Foundation\Tomcat 8.5\bin\Tomcat8w.exe)

I've added note about this workaround into configuration and release notes:

I tried to find, how to fix it another way, i was not successful (i can set this property programmatically). We are using flyway 4.0, maybe new version will help, but i don't find an info about this bug in release notes. I leave this ticket open, if we will have some time to update flyway version (or this workaround will be configured programmatically).
Note: cannot be reproduced on environment:
Fedora 24
java version "1.8.0_51"
Java(TM) SE Runtime Environment (build 1.8.0_51-b16)

Note: After all the flyway scripts were executed, I can start the application correctly without that added Java option. It looks like the problem exists only when the flyway script is applied during the first startup (after upgrade).
Since the problem didn't occur during previous upgrades, there could be some connection with the name/numbering of the 2 scripts added in the version 7.8.3.

I checked syntax for all scripts and they seem to be correct:

I see it now:
...
V7_08_003__add-login-count-and-date-nullable.sql
V8_00_004__eav-short-text-type-indexes.sql
...
This could make this problems, i overlooked it.

I've added missing scripts V8_00_001 - V8_00_003 (just empty files). Files are ignored when installed version is higher than 7.8.0 (=> V8_00_004 and higher is applied), but this should help for future versions, when app is installed.

I checked this behavior on my local clean environment without setting property: -Djava.util.Arrays.useLegacyMergeSort=true and also on clean installation windows server 2016 and both cases works well! Thank you.
This ticket can be probably closed.

New script into versio 8 was added (V8_00_007), else script were aplied -> and now startup fails on my machine too, it's strange. So adding missing scripts didn't help.
