[rules-users] Is protobuf cache actually used?

[Edson Tirelli]

   It is a bit convoluted, indeed, but AFAIK, it is using the cache
and working fine. The cache is populated here:

https://github.com/droolsjbpm/drools/blob/master/drools-compiler/src/main/java/org/drools/compiler/kie/builder/impl/AbstractKieModule.java#L301

   It is set here:

https://github.com/droolsjbpm/drools/blob/master/drools-compiler/src/main/java/org/drools/compiler/kie/builder/impl/AbstractKieModule.java#L180

   And we have some tests here:

https://github.com/droolsjbpm/drools/blob/master/drools-compiler/src/test/java/org/drools/compiler/integrationtests/KieCompilationCacheTest.java
