        Description

        JDK-8173390 introduced significant performance drop (3-4%) on all platforms for SPECjvm2008-XML benchmark.
        JDK-8173390 change resets the SymbolTable. It seams that the performance test reuses the parser and it is re-creating the SymbolTable instead of reusing it.
        To address this issue new system property should be added to control symbol table reset operation.
