* Modify sandbox tasks to implement both java.Function and sandbox.Function.
* Make TaskExecutors implement BiFunction to make them composable.
* Create ImportTask to wrap a java.Function inside a sandbox.Function.
* Add createExecutor() and createRawExecutor() APIs to SandboxClassLoader.
* Update serialization to use SandboxClassLoader.toSandboxClass().
* Remove a layer of lambdas from the serialisation code.
* Update SandboxExecutor and SandboxRawExecutor.
* Rename Executor to TaskFactory.
* Rename dangling executor -> taskFactory.
* Update DJVM Example project for serialisation.
* Add serializers for InputStream and OpaqueBytesSubSequence.
* Support ZIP Inflater and CRC32 inside the sandbox.
* Allow the DJVM to wrap java.io.InputStream as sandbox.java.io.InputStream.
* Configure tests also to preserve @DeprecatedConstructorForDeserialization.
* Create DJVM serialization modules.
* Create test cases for Array<T>, List<T> and List<Array<T>>.
* Refactor SandboxPrimiveSerializer for all primitive types.
* Implement SandboxCollectionSerializer to support Collection types.
* Implement SandboxMapSerializer to support Map types.
* Attempt to fix infinite loop when computing Collection and Map fingerprints.
* Apply special handling when deserialising sandbox.java.lang.Character.
* Remap Java primitive types to sandbox Java object types to deter evolution.
* Use Class.getPackage().getName() to determine sandbox package name.
* Implement SandboxEnumSerializer to support Enum types.
* Implement SandboxPublicKeySerializer to support Java security keys.
* Add serialization projects to the composite example project.
* Implement serializers for BigInteger, BigDecimal, Currency and StringBuffer.
* Test that deserialising does not instantiate the untrusted user classes.
* Implement serializers for java.time.* types.
* Add serialiser for BitSet - currently disabled until BitSet itself is supported.
* Add serialisers for EnumSet and Class.
* Include support for EnumMap in the SandboxMapSerializer.
* Ensure the DJVM Example project's tests preserve @CordaSerializable.
* Add support for UUID as a primitive type.
* Use common abortReadOnly() method for declaring serialization as unsupported.
* Streamline the API for deserialising into the sandbox.
* Add preliminary support for deserialising X.509 certificates.
* Implement serializer for java.util.Optional.
* Refactor configuration of the sandbox serialization scheme.
* Add tests for deserialising arrays of basic types.
* Include method annotations in annotation stitching. This ensures that `@ConstructorForDeserialization` is not dropped.
* Enable test for SandboxBitSetSerializer.
* Enable tests for X.509 serializers.
* Implement serializers for ProtonJ primitive types.
* Serialize java.util.Date as a primitive type.
* Add the bintray Gradle plugin to the serialisation modules.
* Do not publish serialisation modules - they will become part of Corda itself.
