I received this error in CommandBox when calling systemCacheClear( "all" ) after updating to 22.214.171.124.
The error doesn't happen all the time, but there must be some scenario where the NPE happens. I've never seen this error prior to 5.3.5
this is fixed as part of this ticket
Problem was with the move of using SofReferences and we missed to check if they exist or not, we did check ALL uses of SoftReference for this.
Can someone update the fix version for this?
