Pavel Afremov updated HARMONY-5714:
-----------------------------------

    Attachment: remove_extra_monitors_helper_3.patch

Patch was updated.
Getting java.lang.Class object was moved to a separate opcode. Entering and exiting into static monitors, switched to use this new opcode.
But previous scheme are not deleted, so synchronization can be switched back, at any time.
