Hi Rory, Thanks, too! Maybe we can merge those tools in the future! If you have a pointer to the source code of your tool (I assume it also uses ASM internally), I can have a look.
About your initial question, I can confirm: Lucene and Solr do not use any internal JDK APIs directly. If we need to use them (like Unsafe to discover some internal JVM properties for RAM accounting or to unmap mmapped files), it is done solely using reflection and with proper fall back and error handling.
