What Does This Do

Support using dd-instrument-java to inject helper classes.

This uses an instrumentation-based approach to access defineClass rather than Unsafe.

Note that we enable class injection in Agent so any product can use this feature - it is no longer limited to instrumentations. It also provides the ability to inject classes into the boot-loader.

Motivation

Removes one more use of Unsafe from the codebase.

Additional Notes

The previous unsafe-based class injection can be re-enabled with this JVM argument:

-Ddd.unsafe.class.injection=true

or by setting this environment variable:

DD_UNSAFE_CLASS_INJECTION=true
