Are you on macOS, by any chance?

@half-cambodian-hacker-man windows7

my friends say this works fine on 1.8.0/211
maybe they patched this.

i could find symbol gHotSpotVMStructs in the Vm.dll .May be jvm add some limits in addresses reading in newer version of java

Okay I know the reason.
Vm won't share jvm.dll it used already to us.
We could only load it by our self.

I Hijecked
java/lang/ClassLoader$NativeLibrary#onload
It only print Zip.dll

That's the reason.I don't know what's wrong what 1.8.0/211

From my testing on Linux, you don't need to load the libjvm.so manually, but maybe you do for Windows?

Try locating the libjvm.dll and calling System.load() with its location, before you try to get the symbols.

edit: I see that you are already doing this, never mind.

@half-cambodian-hacker-man Okay.Maybe you should add a check to detect this.
It works fine after I load VM.dll into my APPClassLoader
