java regular Expression for splitting a string

I have a string like below, want to split it based on a condition.

|RECEIVE|Low| eventId=139569 msg=W4N Alert :: Critical : Interface Utilization for GigabitEthernet0/1 90.0 % in=2442 out=0 categorySignificance=/Normal categoryBehavior=/Communicate/Query categoryDeviceGroup=/Application

after the split it should look like this

|RECEIVE|Low| 
 eventId=139569 
 msg=W4N Alert :: Critical : Interface Utilization for GigabitEthernet0/1 90.0 % 
 in=2442 
 out=0 
 categorySignificance=/Normal 
 categoryBehavior=/Communicate/Query 
 categoryDeviceGroup=/Application

the condition is identify the space before key=

You can split using this regex (?=\s\w+=)

String str = "|RECEIVE|Low| ... p=/Application";
String[] spl = str.split("(?=\\s\\w+=)");

Outputs

|RECEIVE|Low|
 eventId=139569
 msg=W4N Alert :: Critical : Interface Utilization for GigabitEthernet0/1 90.0 %
 in=2442
 out=0
 categorySignificance=/Normal
 categoryBehavior=/Communicate/Query
 categoryDeviceGroup=/Application
