hg: valhalla/valhalla: 8191766: [MVT] OSR compilation fails with "assert(tk->is_loaded()) failed: must be loaded"

[Tobias Hartmann]

Hi,

when OSR compiling a method with an unloaded argument, the interpreter state can contain an unloaded klass. The assert
I've added to GraphKit::gen_checkcast with JDK-8183111 is too strong [1]. I've pushed this trivial fix without review.

Thanks,
Tobias
