java - My library on multiples connections with my JNI applications -

i developing java application uses c++ library. application type client/server rcp (eclipse plugin based). problem when try connect more 2 clients server, frozes. strange problem happens, when running in windows. in linux, works fine.

i want notice also, that, programatically, clients represented c++ threads. may be, want access same resource. if let application running, waiting defroze, crashes , generates log shown below

libtlmdevice_ycp-3-0-0.dll library using

if have idea :) in advance.

kind regards, ali.

the native code needs attach jvm using attachcurrentthread , use jnienv pointer provided function. cannot use first jnienv c++ lib got hands on.

also, there's chance c++ lib isn't thread-safe, can't tell without seeing source.
