Simply assigning finalValue to value just gives you two pointers to the SAME block of memory. Then in the next line you release this block of memory so finalValue is no longer pointing to a valid block of memory.<br />

- points to objects<br />

<div class="content wysiwyg-content">
jstring str;<br />
char *value;<br />
<br />
value = (char *) (*env)-&gt;GetStringUTFChars(<wbr /> env,str,NULL);<br />
(*env)-&gt;ReleaseStringUTFCh<wbr />ars(env,st<wbr />r,value);<br />
<br />
Above piece of code gets executed for each field of an Java object. It gives a core dump after executing successfully for some field at one specefic point.<br />
<br />
Re-arranging the position of the field also gives the error after certain number of execution.<br />
<br />
I don't do anything with the value as well, just retrieve it and then release it. It still gives an error.<br />
<br />
<br />
Any pointer?????????????

JNI Problem - GetStringChars giving core dump after few repititve operation

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
