Hi Jmix Team,
I encountered the following issue when running my project:
Caused by: java.lang.IllegalArgumentException: Comparison method violates its general contract!
at io.jmix.flowui.sys.AbstractBasePackageConfigurationSorter.sort(...)
at io.jmix.flowui.impl.ActionsImpl.postConstruct(ActionsImpl.java:95)
As a temporary workaround, I applied the following JVM option (based on a suggestion from Claude), which resolves the issue:
-Djava.util.Arrays.useLegacyMergeSort=true
However, I understand this is not a permanent fix.
Could you advise on the possible root causes of this issue? Specifically:
- Could this be related to inconsistent or non-transitive comparator logic in
AbstractBasePackageConfigurationSorter? - Are there known issues with certain Java versions or FlowUI configurations that might trigger this behavior?
- Is there a recommended fix or configuration change to address this properly?
Appreciate your guidance on this.
Thank you.
