java.lang.reflect.Field.getValue() does not work in OSGi environment
Hi,
I meet a problem that looks quite weird for me. I report it here to see
whether people have similar experience.
In hibernate, there is a class
org.hibernate.property.DirectPropertyAccessor$DirectGetter, which is used to
directly access a field's value of a domain class. I find this function
fails in osgi environemt because java.lang.reflect.Field.getValue() throws
IllegalArgumentException, which never happen in non-osgi environment. I
conjecture that this exception has something to do with classloaders. But I
cannot really figure it out. The following is the exception trace.
caused by: java.lang.IllegalArgumentException: Can not set java.lang.Object
field as.classifier.Classifier.oid to xs.personnel.Citizen$Identity$Type
at
sun.reflect.UnsafeFieldAccessorImpl.throwSetIllegalArgumentException(UnsafeFieldAccessorImpl.java:146)
at
sun.reflect.UnsafeFieldAccessorImpl.throwSetIllegalArgumentException(UnsafeFieldAccessorImpl.java:150)
at
sun.reflect.UnsafeFieldAccessorImpl.ensureObj(UnsafeFieldAccessorImpl.java:37)
at
sun.reflect.UnsafeObjectFieldAccessorImpl.get(UnsafeObjectFieldAccessorImpl.java:18)

Yes, you are right. I just do not import a package because the package is
not in the import statements of the java file and hence bnd does not have it
included in the MANIFEST.MF. Thanks.

Hello!
Do you have "Export-Package: xs.personnel" in your bundle?
