When an EnumSet is is serialized on a Sun JDK and then then deserialized on an IBM JDK you'll run into IllegalStateException: "No standard field found for reverse order comparator!" at org.jboss.marshalling.river.Protocol.<clinit>(Protocol.java:216)

Background:

There is a three node infinispan cluster all running Sun JVMs. A forth node is added running an IBM JVM.

While executing the following method:

public List<Consumo> getConsumos(ConsumoFilter filter)

{ Properties props = new Properties(); props.put("infinispan.client.hotrod.server_list", "10.250.2.38:11222"); CacheContainer cacheContainer = new RemoteCacheManager(props); Cache<String, String> cache = cacheContainer.getCache(); cache.put("car", "ferrari"); // In this line there is an exception in IBM JRE ...}

Using JRE ibm-java-i386-60 the following exception appears:

...
Caused by: java.lang.IllegalStateException: No standard field found for reverse order comparator!
at org.jboss.marshalling.river.Protocol.<clinit>(Protocol.java:216)
at java.lang.J9VMInternals.initializeImpl(Native Method)
at java.lang.J9VMInternals.initialize(J9VMInternals.java:200)
... 57 more

In org.jboss.marshalling.river.Protocol there is a statitic initializer:

/* */ static final Class<?> reverseOrder2Class = Collections.reverseOrder(Collections.reverseOrder()).getClass();
/* */ static
/* */ {
/* */ Class clazz;
/* */ try
/* */

{ /* 203 */ clazz = Class.forName("java.util.EnumSet$SerializationProxy"); /* */ }

catch (ClassNotFoundException e)

{ /* 205 */ throw new IllegalStateException("No standard serialization proxy found for enum set!"); /* */ }

/* 207 */ enumSetProxyClass = clazz;
/* 208 */ Field field = null;
/* 209 */ for (Field declared : reverseOrder2Class.getDeclaredFields()) {
/* 210 */ if (declared.getName().equals("cmp"))

{ /* 211 */ declared.setAccessible(true); /* 212 */ field = declared; /* */ }

/* */ }
/* 215 */ if (field == null)

{ /* 216 */ throw new IllegalStateException("No standard field found for reverse order comparator!"); /* */ }

/* 218 */ reverseOrder2Field = field;
/* */ }

The bug is produce cause the class reverseOrder2Class does not have the field "cmp"
In JRE java-6-sun-1.6.0.26, the class reverseOrder2Class is:

private static class ReverseComparator2<T> implements Comparator<T>, Serializable
{
private static final long serialVersionUID = 4374092139857L;

/**

• The comparator specified in the static factory. This will never
• be null, as the static factory returns a ReverseComparator
• instance if its argument is null.
  *
• @serial
  */
  private Comparator<T> cmp;

ReverseComparator2(Comparator<T> cmp)

{ assert cmp != null; this.cmp = cmp; }

public int compare(T t1, T t2)

{ return cmp.compare(t2, t1); }

}

In JRE ibm-java2-60, the class reverseOrder2Class is:

private static final class ReverseComparatorWithComparator<T> implements Comparator<T>, Serializable {
private static final long serialVersionUID = 4374092139857L;

private final Comparator<T> comparator;

ReverseComparatorWithComparator(Comparator<T> comparator)

{ super(); this.comparator = comparator; }

public int compare(T o1, T o2)

{ return comparator.compare(o2, o1); }

}
