According to the specification for PrintStream.print(char), the following two
programs are required to have identical behavior when the default output
encoding is ASCII, UTF8, ISO8859-1, or any other encoding that translates an
ASCII character to its corresponding byte. However, these two programs have
different output. PrintStream.print(char) is improperly flushing the output,
in violation of its specification.

There are many other methods in PrintStream that violate their spec in exactly
this manner. See, for example, print(boolean) and print(int).
