`Client.execute` in Java interface is now strongly typed: returned TDLib object type depends on the return type defined in the corresponding Function class.
When TDLib error is occurred, method now throws `Client.ExecutionError`.
This change adds compile-time protection against return type change and allows using this pattern:
```
try {
TdApi.SpecificReturnType result = Client.execute(function);
// work with strongly typed resultl without casting and type checks
} catch (Client.ExecutionError error) {
// Handle error
}
```

TDLib Java example
To run this example, you will need installed JDK >= 1.6. For Javadoc documentation generation PHP is needed.
You can find complete build instructions for your operating system at https://tdlib.github.io/td/build.html?language=Java.
In general, the build process looks as follows.
TDLib should be prebuilt with JNI bindings and installed to local subdirectory td/ as follows:
cd <path to TDLib sources>
mkdir jnibuild
cd jnibuild
cmake -DCMAKE_BUILD_TYPE=Release -DTD_ENABLE_JNI=ON -DCMAKE_INSTALL_PREFIX:PATH=../example/java/td ..
cmake --build . --target install
If you want to compile TDLib for 32-bit/64-bit Java on Windows using MSVC, you will also need to add -A Win32/-A x64 option to CMake.
In Windows, use vcpkg toolchain file by adding parameter -DCMAKE_TOOLCHAIN_FILE=<VCPKG_DIR>/scripts/buildsystems/vcpkg.cmake
After this you can compile the example source code:
cd <path to TDLib sources>/example/java
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release -DTd_DIR=<full path to TDLib sources>/example/java/td/lib/cmake/Td -DCMAKE_INSTALL_PREFIX:PATH=.. ..
cmake --build . --target install
Compiled TDLib shared library and Java example after that will be placed in bin/ and Javadoc documentation in docs/.
After this you can run the Java example:
cd <path to TDLib sources>/example/java/bin
java '-Djava.library.path=.' org/drinkless/tdlib/example/Example
If you receive "Could NOT find JNI ..." error from CMake, you need to specify to CMake path to the installed JDK, for example, "-DJAVA_HOME=/usr/lib/jvm/java-8-oracle/".
If you receive java.lang.UnsatisfiedLinkError with "Can't find dependent libraries", you may also need to copy some dependent shared OpenSSL and zlib libraries to bin/.
Make sure that you compiled the example for the same architecture as your JVM.
