Having found this :
https://github.com/xwiki/xwiki-platform/commit/662163a5bd7f5d21085e41aa9b530df86f87870e,
... I tried as indicated to use "safe mode" for this particular migration,
so I added the following to my xwiki.cfg and restarted:
xwiki.store.migration.R40000XWIKI6990.safemode=1
It still fails, though exception stacktrace is slightly different (breaks on
line 1127 instead of 777) :
Caused by: java.lang.NullPointerException: null
at
com.xpn.xwiki.store.migration.hibernate.R40000XWIKI6990DataMigration.hibernateMigrate(R40000XWIKI6990DataMigration.java:1127)
~[xwiki-platform-legacy-oldcore-4.1.3.jar:na]
at
com.xpn.xwiki.store.migration.hibernate.AbstractHibernateDataMigration.migrate(AbstractHibernateDataMigration.java:109)
~[xwiki-platform-legacy-oldcore-4.1.3.jar:na]
... 57 common frames omitted
(I omitted the rest of the logs that are almost identical)
In fact it breaks on an identical line but in alternate condition (for safe
mode):
// Skip classes that will be updated by cascaded updates
if (!this.fkTables.contains(klass.getTable())) {
...
Thanks,
Jeremie
