I did some manual benchmarking and created two sets of 100 no-op Jtreg tests. The first set references compiled j.l.classfile.ClassModel and the second set references org.objectweb.asm.ClassWriter declared as a @library.
The difference in execution of the tests is ~3 seconds on my computer (~30ms per test).

Given the limited number of tests affected, I would estimate that the overall performance regression will be in the single digit seconds range.
