Hi Andrew,
Would it be sufficient to export the InitializeEncoding entry point?
Introducing a JNU_xx name may imply a level of support that is
unwarranted since
it is part of system initialization and may change as needed by the
implementation.
Simply exporting it would put it on par with Canonicalize.
Thanks, Roger

Hi Roger,
The OpenJ9 VM implementation provides its own java.lang.System, which
performs similar type early-on VM initialization to the OpenJDK core
library classes. The basic reason for invoking the method is to
initialize the platform encoding either called from a related core
library method, eg.initProperties(), or from the VM in the early
stages of initialization.
My suggested comparison with canonicalize was based on it's indicated
usage:
/*
* Export the platform dependent path canonicalization so that
* VM can find it when loading system classes.
* This function is also used by the instrumentation agent.
*/
extern int canonicalize(char *path, const char *out, int len);
JNIEXPORT int
Canonicalize(JNIEnv *unused, char *orig, char *out, int len)
{
/* canonicalize an already natived path */
return canonicalize(orig, out, len);
}
Many thanks,
Andrew
