---------------------------------------------
Summary: withObjectInputStream(ClassLoader) fails with
ClassNotFoundException for serialized primitive classes such as int.class
Key: GROOVY-12676
URL: https://issues.apache.org/jira/browse/GROOVY-12676
Project: Groovy
Issue Type: Bug
Affects Versions: 5.0.8, 4.0.33, 6.0.0, 7.0.0-alpha-1
Reporter: Scott Murphy Heiberg
{code:groovy}
def bytes = new ByteArrayOutputStream()
bytes.withObjectOutputStream { it.writeObject([int.class, void.class]) }
new
ByteArrayInputStream(bytes.toByteArray()).withObjectInputStream(getClass().classLoader)
{ it.readObject() }
// also: a dehydrated closure with a primitive parameter, whose parameterTypes
holds int.class
bytes = new ByteArrayOutputStream()
bytes.withObjectOutputStream { it.writeObject({ int x -> x + 1 }.dehydrate()) }
new
ByteArrayInputStream(bytes.toByteArray()).withObjectInputStream(getClass().classLoader)
{ it.readObject() }
{code}
*Actual:* {{java.lang.ClassNotFoundException: int}}. The same applies to the
File and Path variants, and to the {{clone()}} generated by
{{@AutoClone(style=SERIALIZATION)}} for a class holding a primitive Class or
such a closure.
*Expected:* {{[int, void]}} and a working closure, as with
{{withObjectInputStream}} without a class loader.
Cause: {{IOGroovyMethods.newObjectInputStream(InputStream, ClassLoader)}}
overrides {{ObjectInputStream.resolveClass}} with {{Class.forName}}, which
cannot load primitive types. The JDK implementation falls back to a table of
primitive types when {{Class.forName}} fails; the override has no such fallback.
Verified on 4.0.33, 5.0.8, 6.0.0 and master.
