thanks for the information! I checked a couple of char[] an yes, I found a
couple of String-objects that hold the char[] as value-reference. For
example I checked a char[] with a retained heap size of 63,968 bytes and
found two String-objects each with a count of 30.
Somehow this seems to me like a huge design problem of the sun jvm's, but
I think I'm overlooking something very important ;)
