Hi,
Please, help to review the fix [1] for a performance regression in
SPECjvm2008-XML benchmark. The cause of this regression was the
unconditional reset of SAX parsers symbol table during each reset()
operation introduced by JDK-8173390.
Proposed fix introduces new system property (CCC request is still
pending approval) that provides ability to control the symbol table
reset functionality. By default the reset table functionality is
disabled, similar to pre JDK-8173390 behavior. JAXWS parsers pool
implementation was updated to utilize new property to reset symbol table
only in JAXWS use-cases that helped to restore the performance levels to
pre JDK-8173390 level.
Modified regression test and XML related JCK tests passes on build with
proposed changes.
With Best Regards,
Aleksei
