Original link: Broadcom pledges to lock down open source Python, Java libraries / TheRegister.
Broadcom bought VMWare and besides all the commercial applications then VMWare also maintained some very important open source pieces including Spring and RabbitMQ.
Now Broadcom has committed to maintain those to keep them secure.
Spring is a family of Java libraries - most Java programs use one or more Spring libraries. RabbitMQ is a widely used message queue.
