The synchronization block may be substituted by the 'volatile' variable smaller synchronization block. It reduce the total blocking time for the specjvm2008::xml.validation workload and improve the reported score. Scores for the 112vCPU on the with 28GB heap increased from 17915.83 to 22943.2. Unit tests was not affected: Test summary ============================== TEST TOTAL PASS FAIL ERROR jtreg:test/jaxp 516 516 0 0 jtreg:test/jdk/javax/xml 70 70 0 0 ============================== TEST SUCCESS
