<description>
Partially created objects can be returned by the Double Checked Locking pattern when used in Java.
An optimizing JRE may assign a reference to the baz variable before it calls the constructor of the object the
reference points to.
Note: With Java 5, you can make Double checked locking work, if you declare the variable to be `volatile`.
For more details refer to: &lt;http://www.javaworld.com/javaworld/jw-02-2001/jw-0209-double.html>

externalInfoUrl="${pmd.website.baseurl}/pmd_rules_java_multithreading.html#nonthreadsafesingleton">
<description>
Non-thread safe singletons can result in bad state changes. Eliminate
static singletons if possible by instantiating the object directly. Static
singletons are usually not needed as only a single instance exists anyway.
Other possible fixes are to synchronize the entire method or to use an
[initialize-on-demand holder class](https://en.wikipedia.org/wiki/Initialization-on-demand_holder_idiom).
Refrain from using the double-checked locking pattern. The Java Memory Model doesn't
guarantee it to work unless the variable is declared as `volatile`, adding an uneeded
performance penalty. [Reference](http://www.cs.umd.edu/~pugh/java/memoryModel/DoubleCheckedLocking.html)

<description>
Thread.notify() awakens a thread monitoring the object. If more than one thread is monitoring, then only
one is chosen. The thread chosen is arbitrary; thus its usually safer to call notifyAll() instead.
