You can change the startup parameters of IntelliJ to reduce the maximum memory usage. If you don't it will optimize for least GC time rather than least memory usage and maximum usage will be 75% of total memory.

With java 12 you'll be able to tweak G1 to minimize footprint without setting an arbitrary maximum.

I bet ZGC would also be pretty great for this use case as it is super conservative.
