</code></pre><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>If I do the same for JavassistTypeInfo, then that will load the class. Is that a bad thing? Probably...</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>The alternative for this simple implementation to work is to save the name and the classloader, and classloaders are not serializable.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Or am I missing something? When deserializing a class should that happen in the same classloader (or one with access to similar classes if serialized out of the vm) as the one that serialized it in the first place? If the answer is yes, then I can go forward with this.</p><div> </div></div>
