There is a size limit of Java class (64k), which is described with details in this question: maximum size of java class / exception table
So it's a hard limit, which should not be overriden (if the internal addresses are 2 byte, it could be even theoretically not possible).
In the topic _jspService is exceeding the 65535 bytes limit the recommended solution is to use dynamic includes instead of static:
<jsp:include page="test.jsp" />
If you have a lot of Java-logic in your page, move it to Java classes.
If you simply have enormous page, and splitting it to many smaller pages is not an option, you can try to move as much as possible to custom tags.
