[jira] [Created] (METAMODEL-241) Deserializing legacy objects fails on some JREs

Kasper Sørensen created METAMODEL-241:
-----------------------------------------

             Summary: Deserializing legacy objects fails on some JREs
                 Key: METAMODEL-241
                 URL: https://issues.apache.org/jira/browse/METAMODEL-241
             Project: Apache MetaModel
          Issue Type: Bug
    Affects Versions: 4.5.2
         Environment: Windows 7
JDK 1.8.0_77
Happens both via command line build and test runs in eclipse
            Reporter: Kasper Sørensen


I just got myself a new laptop and installed a new development environment. For some reason there seems to be a change in the JRE that causes legacy object deserialization to fail with the following causes:

The failing test is {code}

and underlying I found that in LegacyDeserializationObjectInputStream.isEnumExpected(...) we run into this problem which causes the rest of the deserialization to go wrong:
