dear all, this is my first post, so if there are something wrong, pls to
As for biased locking, we know that when one thread has got an object's lock
use biased pattern, when the thread want to got the lock again(the thread
don't relase the lock at that time), hotspot just to find the thread has
already owned the lock and do nothing( at least not change the object's
header), could anyone told me where i can find the code to deal with this
recursive locking situation. I had read
synchronize.hpp(cpp),biasedLocking.hpp(cpp), but find nothing, i think the
fast_enter() function in the synchronize.cpp didn't deal this case(The
openjdk's version i got is openjdk-7-ea-src-b136-31_mar_2011). Any
suggestion is appreciated!
