Sun GlassFish Enterprise Server 2.1 Release Notes

TopLink expects my `Collection` field/property to be cloneable (Issue Tracker 556)

Description

If the java.util.Arrays.asList() API is used to convert an Object[] to Collection, the JDK returns an implementation of java.util.ArrayList that is not cloneable. This results in the following exception:

The method invocation of the method [protected native java.lang.Object 
java.lang.Object.clone() throws java.lang.CloneNotSupportedException] on the object 
[[pkg.A id = xxx]], of class [class java.util.Arrays$ArrayList], triggered an 
exception. Internal Exception: java.lang.reflect.InvocationTargetException Target 
Invocation Exception: java.lang.CloneNotSupportedException: 
java.util.Arrays$ArrayList

This issue is tracked at https://glassfish.dev.java.net/issues/show_bug.cgi?id=556.

Solution

Create another collection using its constructor; for example:

myCollection = new ArrayList(java.util.Arrays.asList(a))
