> [JDK-8294961](https://bugs.openjdk.org/browse/JDK-8294961) changed to use classfile API for reflection proxy-generation. Actual implementation of `ProxyGenerator` is focused on performance, however it causes JDK bootstrap regressions. `ProxyGenerator.TEMPLATE` class model is statically created and each proxy class is transformed from the template.
>
> This patch is intended to examine plain proxy generation impact on performance and JDK bootstrap (vs proxy transformation from template).
>
> The generated proxy is migrated from static initialization to CONDY bootstrap.
>
> Please review.
>
> Thank you,
> Adam
