Synchronized Statements in StrictXmir.java Require Replacement for Optimal Performance

[0pdd]

The puzzle 4884-4327f48e from #4884 has to be resolved:

eo/eo-parser/src/main/java/org/eolang/parser/StrictXmir.java

Lines 47 to 52 in 3674af6

	* @todo #4884:30min Replace synchronized statements with ReentrantLock.
	* We are getting the following complaint about {@ling StrictXmir}:
	* StrictXmir.java[244-289]: Use ReentrantLock rather than synchronization
	* (AvoidSynchronizedStatement). It's better to consider this replacement.
	* Don't forget to remove PMD.AvoidSynchronizedStatement from the
	* SuppressWarnings annotation of this class.

If you have any technical questions, don't ask me, submit new tickets instead. The task will be "done" when the problem is fixed and the text of the puzzle is removed from the source code. Here is more about PDD and about me.
