An internal static analysis tool detected a potential null pointer dereference in SharedClassPathEntry::copy_from in filemap.cpp:

void SharedClassPathEntry::copy_from(SharedClassPathEntry* ent, ClassLoaderData* loader_data, TRAPS) {
  _type = ent->_type;
  _is_module_path = ent->_is_module_path;
  _timestamp = ent->_timestamp;
  _filesize = ent->_filesize;
  _from_class_path_attr = ent->_from_class_path_attr;
...

The ent could be null.
