Instrumentation is not compatible with jdk8

[ShibasishDelphix]

Hi Team,
We upgraded java-allocation-instrumenter from 3.0 to 3.4.0. We use AdoptOpenJdk1.8. Post upgrade
AllocationRecorder.getInstrumentation() in ConstructorInstrumenter is being returned as null. The same was earlier getting mapped to sun.instrument.InstrumentationImpl in v3.0.
Could you please confirm if 3.4.0 is compatible with jdk1.8 and help me.
Thanks.

As far as I know, we still support it: The tests pass with --java_runtime_version=8, and I don't see anything in the release notes about dropping support. (We did document dropping support for Java 7 in 3.3.1, and I don't see anything similar about Java 8.) But Google is on JDK 11+ at this point, so JDK8 isn't getting any real-world testing from us anymore. It's entirely possible that support has regressed. This project doesn't get much attention in general nowadays, so I don't know how likely it is that we'd look into this even if we had a way to reproduce it :(
