Sorry if this is nit-picking but it would be the allocators that would track this.

The tooling question for Java is interesting as this discussion about tooling goes back more than 20 years. It was never the intent of Sun to provide tooling for Java and they actively stayed out of the tooling arena. JMX was forced into the JDK (1.4 time frame by JRockit) as customers were demanding greater visibility. The VisualVM project was really frowned upon as it was seen as a threat to partners who were in the tooling space at that time. As you can see, Oracle as a completely different idea on tooling hence JMC and JFR.
