Thaddeus Diamond created IO-368:
-----------------------------------
Summary: ClassLoaderObjectInputStream does not handle primitive
typed members
Key: IO-368
URL: https://issues.apache.org/jira/browse/IO-368
Project: Commons IO
Issue Type: Bug
Components: Streams/Writers
Affects Versions: 2.0.1
Environment: Single node computer, running standard JVM (Oracle 1.6.0)
Reporter: Thaddeus Diamond
Any class with a simple primitive (such as long, or int) cannot be
deserialized. For example, the following code:
{code:java}
ObjectInputStream ois = null;
try {
ois = new ClassLoaderObjectInputStream(getClass().getClassLoader(), new
ByteArrayInputStream(bytes));
return (T) ois.readObject();
} catch (ClassNotFoundException e) {
LOGGER.error("Deserialization failed for {}", objectClass, e);
} catch (IOException e) {
LOGGER.error("Deserialization failed for {}", objectClass, e);
} finally {
if (ois != null) {
try {
ois.close();
} catch (IOException ignored) {
}
}
}
{code}
Will fail if bytes represents a byte[] of the serialized version of the
following class:
{code:java}
public class Foo {
private static final long serialVersionUID = 1L;
private long thisFieldWillCauseCLOISToFail;
// class logic, ctors, etc...
}
{code}
With the following stacktrace:
