Error building Java example - cannot find symbol

[tashoyan]

When running the second cmake --build command from the build sequence (in the directory example/java/build), I get a failure:

cmake --build . --target install
...

2 errors
make[2]: *** [CMakeFiles/build_java] Error 1
make[1]: *** [CMakeFiles/build_java.dir/all] Error 2
make: *** [all] Error 2

The build fails, because the class TdApi.Chat does not have such attribute: themeName. According to the scheme generate/scheme/td_api.tl, the attribute has the following name: theme. The file Example.java should be updated:

                    synchronized (chat) {
                        chat.theme = updateChat.theme;
                    }

Build environment: MacOS, Intel.
