The gcj garbage collector will recycle memory when it determines that
there are no live references to it. The gc won't look inside
structures allocated by malloc() or the C++ runtime library's new().
If you want to make an array of 'java::lang::String *' you had better
make it a JArray<jstring>, not a C++ array, and you'd better make sure
that a pointer to that jarray is live in a Java object somewhere, or
the strings will be deallocated.
