log4cplus:
- 1.2.0
- Visual Studio 2012
- config: release and debug
- windows 10, i7 4770

client:
- 32 bit Java 7 application
- log4cplus as dll
- log4cplus.lib and log4cplusD.lib
- multibyte chars
- see attached logfiles
- client DLL compile settings: no MFC, no ATL, multibyte charset, /MDd and /MD

We use log4cplus in an custom C++ dll which itself gets dynamically loaded in java program.
during the runtime everything works ok.
At application exit we see an java hotspot error (see logs). 
This happens with and without calling log4cplus::Logger::shutdown();
The problem also occurs if nothing but log4cplus::initialize(); and log4cplus::Logger::shutdown(); are called.

From the hotspot error it looks like an cleanup issue:
