> Currently Jitrino.JET keeps GC info and can enumerate the frame only at call and throw instructions (safe points). However, in JVMTI mode breakpoint may cause thread suspend and GC at almost any instruction so in JVMTI mode Jitrino.JET must keep GC info at each instruction corresponding to every bytecode.
