The following fields are only used by JVMTI:

InstanceKlass::_breakpoints
InstanceKlass::_previous_versions
InstanceKlass::_cached_class_file
InstanceKlass::_jvmti_cached_class_field_map
MethodCounters::_number_of_breakpoints

They can be excluded, along with related code, when INCLUDE_JVMTI==0. This will reduce both static and dynamic footprint for the minimal VM.

This is part of the work for JDK-8138571. It was not explicitly listed, but these changes were included in the changeset for item #8 (JDK-8147978 ).
