Description

While performance-testing Ofbiz 18 under high load (200 concurrent users), we have observed an intermittent error, stating "null DispatchContext".

While doing more analysis, we realized it is a thread-safety issue, and it was fixed by adding the 'synchronized' keyword to the following method signatures in ServiceDispatcher.java:

public static synchronized getInstance (Delegator delegator) 

public static synchronized void register (DispatchContext context)
