hibernate-envers - UnsupportedOperationException

[zyro23]

dbm-3.0.0, grails-3.2.3, gorm-6.0.4, hibernate-5.0.11.

when using hibernate envers, all liquibase commands that involve two databases (e.g. dbm-gorm-diff - 1 gorm db, 1 real db) cause an UnsupportedOperationException here:
https://github.com/hibernate/hibernate-orm/blob/5.0.11/hibernate-envers/src/main/java/org/hibernate/envers/boot/internal/EnversServiceImpl.java#L107

ugly workaround for now was to write a custom ÈnversService / ServiceContributor / ServiceInitiator that overrides the default hibernate EnversServiceImpl.

do we have any sane option to prevent that from happening or should we raise an upstream issue for hibernate-envers explaining the dbm diff use-case and request to remove that condition?

[jameskleeh]

Can you include the stacktrace? I doubt hibernate would consider changing that for our use case.

[zyro23]

sure. gradlew dbmGormDiff only shows: Command execution error: EnversService#initialize should be called only once.
no stacktrace with--debug --stacktrace either.
debugging to https://github.com/hibernate/hibernate-orm/blob/5.0.11/hibernate-envers/src/main/java/org/hibernate/envers/boot/internal/EnversServiceImpl.java#L107 gives the following stack (note the condition only fails if it runs the 2nd time, that is for the GORM diff model):

java.lang.UnsupportedOperationException: EnversService#initialize should be called only once

this is a bit related to grails/gorm-hibernate5#15 as that would at least allow to cleanly override the EnversService used by hibernate by default (EnversServiceImpl) with a custom implementation.

@zyro23 I don't think there is anything I can do on this end. I see the issue you linked is closed. Does that satisfy your requirement?

[zyro23]

linked issue has kind of a follow up as it fixed being able to register a custom service in envers but now the configuration of a custom mappingContextConfiguration is not working. ref. grails/gorm-hibernate5#17

anyway, thats the right place where this should be fixed. closing this one here. thanks!

[RobertStroud]

@zyro23 can you provide more information about your "ugly workaround"? Is this something that needs to be fixed in the "database-migration" plugin, or does it need to be fixed in the interface between Grails and Envers, for example, in an Envers plugin?

I am experiencing the same problem using Grails 3.2.12 with GORM 6.1.6 and a version of the "grails-envers" plugin that has been ported to Grails 3.

Thanks.

I know that this issue was closed a long time ago, but i'm lost in getting dbm-gorm-diff running. Could you please give me some advice how to do it?

Thanks.

Same here, the plugin is broken for grails 4.

Any update at all ?

[verglor]

There is open issue #204 for this.
