[Jikesrvm-researchers] Loading of java.lang.Runnable in optimizing compiler

[David W. <cw...@ui...>]

Hi,

I am working on the optimizing compiler and would like to know whether
it is ok
to do things like
OPT_RVMClassLoaderProxy.findOrCreateType("Ljava/lang/Runnable;")
inside the optimizing compiler. Would it violate the Java classloading
semantics?

Moreover, if the following lines of code are performed within the
optimizing compiler, does
it violate the classloading semantics?  I checked the
VM_Type.isAssignableWith () method
and it seems that the call would trigger class loading.

VM_Type type = ...;
VM_Type runnableType = OPT_RVMClassLoaderProxy.findOrCreateType
    ("Ljava/lang/Runnable;");

if (VM_Type.isAssignableWith (runnableType, type)) {...}

If VM_Type.isAssignableWith () is not classloading-safe, are there any
ways to do similar thing safely?

Thanks,

David
