In deploy/src/plugin/solaris/nscore/remotejni.cpp, there are several places where call malloc but don't call free. The affected methods are:


When doing liveconnect call, mozilla will call jni_NewString to convert js string to java string, sometimes, the js string is very large, it will cause serious mozilla memory growth.

This problem also exists in 1.4.2.

EVALUATION DEFINE_CAPTURESCALARARRAYELEMENTS does not call memory leak, the memory allocated by it will be release by other JNI function. Other functions actually cause memory leak. Also there some mismatched AddRef() and Rlease() , they cause memory leak too ###@###.### 2004-11-25 09:30:48 GMT some leaks also exist in server.c ###@###.### 2004-11-30 11:05:14 GMT
