Java call function from multiple threads not declared thread safe

There is a JDK function which, although javadocs does not declare it thread safe, looking at the code on Google, it seems that I can get the result I want by calling it from multiple threads without unwanted side effects, since the function uses mainly stack variables. Therefore, it does not matter if it has synchronized blocks. I wonder if I am missing something and in the end run into trouble. Function - connection.call (requestMsg, url); SOAPConnection by SAAJ api. Any pointer to how I should parse this to decide whether to use it from multiple threads or not?

Thank!

A general rule is that methods and classes are thread safe unless otherwise indicated. So, for example, RMI methods are thread safe, the same.
