In addition to performing redundant work, this also impacts build reproducibility for native image generators which might already have a strategy to cope with hidden classes but cannot cope with indeterminate definition order for lambda proxy classes.

While I agree with your assessment that this is a much less intrusive solution to JDK-8292914 than the proposed system property, I also take Mandy's concern seriously here.  

I suspect that as Leyden progresses, there will be multiple issues we may want to consider in various bootstrap implementations to make them more amenable to time-shifting.  I propose that we leave this PR on the table to be considered when we take up the issue more holistically, rather than doing it in bits and pieces?
