    Known Issues

    • DB module
      • /rest-v1/db/additional/ upload endpoint can throw exception com.chemaxon.webservices.db.exception.BadChemicalDataInRequestException if idProperty is autogenerated in the case of tables with those molecule types which have tautomer handling mode different than OFF. The relevant parameter of the molecule type is specified in the application.properties file as com.chemaxon.zetor.types[n].tautomerHandlingMode.

    February 23rd 2021: JChem Microservices 21.3.0

    Bugfixes

    • DB module
      • Duplicate and full fragment search failed with some query structures if the molecule type had generic tautomerization method and some custom transformation set in its standaridzer configuration.

    Known Issues

    • DB module
      • If the default schema gcrdb is set in the application.properties file, the additional parameters - taken from JChem Engines cache and memory calculator like com.chemaxon.zetor.settings.molecule.cachedObjectCount are not taken into account. If you want to set these additional parameters, please set com.chemaxon.zetor.settings.scheme= mapdb
      • /rest-v1/db/additional/ upload endpoint can throw exception com.chemaxon.webservices.db.exception.BadChemicalDataInRequestException if idProperty is autogenerated in the case of tables with those molecule types which have tautomer handling mode different than OFF.
