After adding Datahub and SAP Extensions, Backoffice throws an 500 error (Hybris 6.5)

After adding the DAtaHub and SAP Extensions the Backoffice shows a 500 error page.

We are using Hybris 6.5.

The console shows an StackOverflow:`Nov 24, 2017 12:02:55 PM org.apache.catalina.core.StandardWrapperValve invoke SCHWERWIEGEND: Servlet.service() for servlet [zkLoader] in context with path [/backoffice] threw exception [Servlet execution threw an exception] with root cause java.lang.StackOverflowError at java.lang.String.valueOf(String.java:2994) at de.hybris.platform.regioncache.region.impl.DefaultCacheRegionProvider.getRegionsForType(DefaultCacheRegionProvider.java:206) at de.hybris.platform.regioncache.region.DefaultCacheRegionResolver.resolveForGet(DefaultCacheRegionResolver.java:40) at de.hybris.platform.regioncache.DefaultCacheController.resolveCacheRegionForAdd(DefaultCacheController.java:333) at de.hybris.platform.regioncache.DefaultCacheController.getWithLoader(DefaultCacheController.java:234) at de.hybris.platform.cache.impl.RegionCacheAdapter.getOrAddUnit(RegionCacheAdapter.java:212) at de.hybris.platform.tx.Transaction$GlobalCacheAdapter.getOrAddUnit(Transaction.java:2388) at de.hybris.platform.cache.AbstractCacheUnit.get(AbstractCacheUnit.java:175) at de.hybris.platform.persistence.type.AtomicType_HJMPWrapper$FindByCodeExact1FinderResult.getFinderResult(AtomicType_HJMPWrapper.java:1191) at de.hybris.platform.persistence.type.AtomicType_HJMPWrapper.ejbFindByCodeExact(AtomicType_HJMPWrapper.java:1250)`

After login the User can choose between backofficeworkflowadmingroup and the datahubadmingroup. Sometimes choosing the datahubadmingroup the backoffice works.

How can i resolve this problem?

It seems to be a memory problem. Setting the parameter -Xss256K in the local.properties to -Xss512K fixed the error.
