IKVM.NET 0.46 is the last OpenJDK 6 based release, so it will be supported longer than usual. I haven't yet decided how long exactly, but in any case here is a release candidate for an update release that incorporates many of the fixes that have been done since 0.46 was released.

Changes:

• Changed version to 0.46.0.2.
• Bug fix. TypeWrapper.IsAssignableTo() didn't handle arrays with primitive elements properly.
• Bug fix. Exception blocks inside potential try { } finally { } blocks were not handled correctly. Could result in finally blocks that run multiple times (when an exception occurs).
• Fix for #3404229.
• Bug fix. Don't create a miranda method if the class already has a static method with the same signature.
• Added workaround for another x64 JIT bug. See https://sourceforge.net/mailarchive/message.php?msg_id=28250469
• Newer versions of ICSharpCode.SharpZipLib.dll require the ZipEntry size to be set explicitly, otherwise the generated archive will not be compatible with older zip implementations (like Java 6's java.util.zip).
• Fixed serialization interop bugs.
• Bug fix. When an abstract .NET type implements System.IComparable (and hence java.lang.Comparable) the resulting stub is not usable from Java because the compareTo method is missing. This fix adds the missing method.
• Fix and enhancement. When a .NET type implements a shadowed interface, we now also publish the original interface (e.g. if the .NET type implements System.IComparable, Java code will now see java.lang.Comparable and System.IComparable). In addition, the new code makes sure that when a .NET type explicitly implements both System.IComparable and java.lang.Comparable that the Java code will not see java.lang.Comparable twice.
• Bug fix. Make FileOutputStream in append mode always append.
• Add support for overriding constructor body in map.xml.
• Make sure that Thread.getContextClassLoader() and Thread.setContextClassLoader() are JITed before Thread.isCCLOverridden().
• Workaround .NET 2.0 bug in GetType() that could cause problems with creating proxies for compiled types.
• Bug fix. Exceptions declared with ThrowsAttribute(Type) (in .NET code) did not get exported properly by ikvmstub.
• Fix ClassLoader.findLoadedClass0() to handle null string.
• Implemented support for annotation defaults in ikvmstub.
• Bug fix. Final instance fields that have a type 2 access property should also have a (private) setter for reflection and serialization.
• Bug fix. Set os.name and os.version properties correctly when running on unknown Windows version (Windows 8).
• Bug fix. IPInterfaceProperties.GetIPv_Properties() can throw an exception (and does so on Win 8 for some interfaces).
• Don't open the remap file in read/write mode.
• Bug fix. Make sure sun.misc.Launcher is initialized before setting a security manager, because Launcher assumes there is no security manager yet.
• Implemented com.sun.security.auth.module.NTSystem.getCurrent().
• Bug fix. When calling a final method on a remapped type we can't call the instance method in the remapped type, but we have to call the instancehelper instead.
• Fix. When decoding a NameSigAttribute it is possible that a type does not exist (i.e. is an unloadable) and that results in a warning emitted against the referenced assemblies class loader.
• Bug fix. Removed incorrect verifier check for uninitialized objects on backward branch.
• Handle Main-Class manifest value that spans multiple lines. Fix for bug #3461012.
• Retain reflection field ordering for ikvmc compiled code (not required by spec, but to improve compatibility with broken code).
• Don't use "slow path" for field reflection on remapped types (as getting a Throwable field from cli.System.Exception will cause an exception, but the slow path will generate a different exception).
• Backported the new method override resolution code.
