=> this issue is resolved when we launch 100 job through jmeter and one job
was getting failed because multiple thread would try to initialize the variable
even tough the call is made through lazy, but still in multiple thread cases
multiple thread tried to initialize variable, to avoid this added synchronized
block so that only one thread only can initialize the variable and latter for
other thread there's no chance of accessing that block.
