What is the bug?

After I read the data and close the resource using delete, this error message appears when the jvm starts GC and causes the system to crash: OGRFeatureDefn: OGRFeatureDefn xxx with a ref count of -1 deleted!

Steps to reproduce the issue

Layer layer = dataSource.GetLayer(0);
if (layer != null) {
FeatureDefn defn = layer.GetLayerDefn();
//......
Feature feature;
while ((feature = layer.GetNextFeature()) != null) {
//........
}
layer.delete();
}
dataSource.delete();

// Forced trigger GC
System.gc();

@sulongx which input data format do you use, and could you try to create a one file isolated .java reproducer ?
