Thank you for the stack, now I see what the problem is. There is no
recursive call back across the remote bridge (which should have worked).
Instead, osl_waitCondition (called from
cppu_threadpool::JobQueue::enter) is broken in that it calls
PeekMessage, which continues to dispatch Windows events, which in turn
causes the logically blocked UNO thread to make a second, unrelated
remote call, which is not expected to happen per the design of UNO and
consequently leads to disaster.
The PeekMessage was apparently added when fixing
<http://qa.openoffice.org/issues/show_bug.cgi?id=92756>. I re-opened
that issue now.

I don't think dispatchRemote2UnoProxy support reentry, because UNO Remote
Protocol Specification does not allow this:
When sending a synchronous request message with the TID of a UNO thread
h, the sending side will not execute any computation steps in thread h
(especially, it will not send any further request or reply messages with the
given TID), until it receives back the corresponding reply message.
No, this reasoning is not correct. If the receiving side (B) of the
request synchronously calls back to the (originally) sending side (A), A can
also recursively make a second, nested synchronous call to B.
My question are:
1 How to accelerate calls from C++ to java when using java
DispatchProviderInterceptor? Or we made some mistakes?
2 Is there a way to avoid this reentry?
Please check out the dump file attached.
