In jurt/source/pipe/com_sun_star_lib_connections_pipe_PipeConnection.c, handling
of Java exceptions is broken. For example, ThrowException and MonitorExit are
called without a previous call to ExceptionClear, and state ACQUIRED is not
catered for in the error-handling code of
Java_com_sun_star_lib_connections_pipe_PipeConnection_readJNI.
The following is some prototypical code to use:
void native_fn(jobect o) {
if (env->MonitorEnter(o) < 0) return;
// ...
if (env->FindClass("...") == 0) {
// Some Java exception occurred while
// within the monitor, exit the monitor and
// return with a Java exception pending:
jthrowable e = env->ExceptionOccurred();
assert e != 0;
env->ExceptionClear();
if (env->MonitorExit(o) == 0) {
env->Throw(e); // even if Throw returns < 0,
// it is guaranteed that *some*
// exception is being thrown,
// right?
}
return;
}
// ...
env->MonitorExit(o);
}
