There are a few places which check for null-or-empty String, where the empty part is performed with "".equals(). Rather than loading an explicit literal, use isEmpty() on the string itself, as we know it is not null. Signed-off-by: Robert Varga <robert.varga@pantheon.tech>

@ThrawnCA Actually this is faster than using string utils. And this is faster than the check it had. See internals of isEmpty() below. Its just checking the length. Other tools are already flagging the same code (believe sonar at least). |
