Java as a server language has a record of nasty serialization-related RCE vulnerabilities. Of course, they're in popular Java libraries used on the server rather than the language itself, just like this bug was in a popular C library rather than the language itself - but Java makes it very easy to accidentally write that kind of vulnerability. In fact, just loading two unrelated libraries that are individually safe sometimes create an exploitable RCE condition in Java. That's worse than even C.
