getMetaData() after objectLoad() causes NULL POINTER error

Problem Description: In CF 9.0.1 if you perform a getMetaData() call on an object that was just loaded with ObjectLoad() then you will have a NULL POINTER error.  If you call a method of that object, or writedump that object, prior to the getMetaData() call then the getMetaData() call will function correctly.  See StackOverflow ticket for a couple of methods to reliably reproduce.

This is not a problem within Railo.  This has been confirmed within CF 9.0.1, CF 9.0.2, and CF 10.0.9

Steps to Reproduce:

I have attached 2 files.  NullError.cfc and NullErrorTest.cfc.  If you run the MXUnit tests within NullErrorTest.cfc then the error will reproduce.

Alternatively another user has found the following will also reproduce the error

// C.cfc
component {}

<!--- test.cfm --->
o1 = new C();
writeDump(getMetaData(o1)); // OK

o2 = objectLoad(objectSave(o1));
writeDump(getMetadata(o2)); // breaks

Actual Result:


Expected Result:

Metadata dump of component object

Any Workarounds:

1 : WriteDump(o2) prior to doing GetMetaData(o2)
2 : Calling a method of o2 prior to GetMetaData(o2)

Both these workarounds result in the object behaving correctly following an ObjectLoad

This is reproducable on any CF 9.0.1 environment  (Linux + Win) that I have tried so far.  Another user has also tested 9.0.2 and 10.0.9 and found this same issue to be reproducable in that.
