-------------------------------------
Resolution: Fixed
Thanks for your updated patch, Tommas. It's applied
> ClassCastException while serializing byte[] in Sling Job with JCR Resource
> Resolver

> Key: SLING-3140
> URL: https://issues.apache.org/jira/browse/SLING-3140
> Project: Sling
> Issue Type: Bug
> Components: JCR
> Affects Versions: JCR Resource 2.2.8
> Reporter: Tommaso Teofili
> Assignee: Carsten Ziegeler
> Fix For: JCR Resource 2.3.0
>
>
> When trying to serialize a byte[] in Sling Job properties Map I noticed that
> an error occurs when using the JCR Resource Resolver caused by a
> ClassCastException in JcrPropertyMapCacheEntry since it tries to cast a byte
> to Object. This therefore doesn't happen when serializing Byte[].
> This also happens when trying to serialize long/int/...[] due to the same
> cast.
> Here's the stacktrace:
> could not add an item to the queue java.lang.ClassCastException: [B cannot be
> cast to [Ljava.lang.Object;

> properties.put("BIN","a string".getBytes());
> Job job = jobManager.addJob("name", "id", properties);
> See testcase below to reproduce the problem on the JCR Resource Resolver:

> import org.junit.Test;
> public class JcrPropertyMapCacheEntryTest {
> @Test
> public void testByteArray() throws Exception {
> Byte[] ba = new Byte[0];
> new JcrPropertyMapCacheEntry(ba, null);
> // ok
> byte[] ba2 = new byte[0];
> new JcrPropertyMapCacheEntry(ba2, null);
> // fail
> }
> @Test
> public void testLongArray() throws Exception {
> Long[] ba = new Long[0];
> new JcrPropertyMapCacheEntry(ba, null);
> // ok
> long[] ba2 = new long[0];
> new JcrPropertyMapCacheEntry(ba2, null);
> // fail
> }
> }
