# Error description
I am using ecoinvent_391_apos_upr_n3_20230629 to calculate the impact assessment of a simple input-output 3 strep process. The direct calculation for the unit process is working fine, but when calculating product system, this error is occurring. Earlier OpenLCA was crashing while using ecoinvent_3.7 and newer versions, but as I updated my java to jdk 21, it is working, but only for unit process.
