Bytecode rewriting agents have the power to inject code into classes; they
should somehow also be able to reflectively inspect those same classes!
But how? We ran into similar problems trying to port java agents at Google
to jdk9.
On the general point: agents (both java and JVM TI agents) can redefine
any module in support of instrumentation and any amount of deep
reflection that the agent might do. So I wouldn't expect too many issues
although some java agents may need updates to work on JDK 9 without
encapsulation busting command line options.
On Byteman, Andrew Dinn has been working with us on jigsaw-dev on the
agent support. From the stack trace then I suspect the issue you are
running into is that Byteman has also changed to use the new reflection
API (java.lang.invoke) and is running into a long standing check to
prevent full power lookups to full privileged classes from leaking.
Andrew brought this up on jigsaw-dev [1] a few days ago and we could
probably move that thread to core-libs-dev.
