-----------------------------------
Summary: Custom arrays are not serialized/deserialized properly by
CacheObjectBinaryProcessorImpl
Key: IGNITE-3244
URL: https://issues.apache.org/jira/browse/IGNITE-3244
Project: Ignite
Issue Type: Bug
Components: cache
Affects Versions: ignite-1.4
Reporter: Denis Magda
Assignee: Denis Magda
Priority: Critical
Fix For: 1.7
If to put a custom object array into a cache like this one
{code}
TestObject[] arr = new TestObject[] {new TestObject(i)};
cache.put(0, arr);
{code}
then it will be serialized as Object[] array in
{{CacheObjectBinaryProcessorImpl.marshallToBinary}} method.
This leads to the situation when object's array type is lost and on cache.get
the code below produces {{ClassCastException}}
{code}
TestObject[] obj = cache.get(i);
{code}
The full test is already added into
{{GridCacheBinaryObjectsAbstractSelfTest.testCustomArrays}}.
To fix the issue we have to revisit logic of
{{CacheObjectBinaryProcessorImpl.marshallToBinary}} and
{{CacheObjectContext.unwrapBinary}}.
