Encountered the above while parsing an XML file in ColdFusion.
Root of the problem:
This is a limitation of Java. A classfile may not exceed 65535 bytes. ColdFusion compiles CFML into Java bytecode, and each method gets its own .class file. (Look in WEB-INF/cfclasses) There does not appear to be a way to increase this limit.
Why we saw this error:
For convenience, we have some pound-delimited variables scattered through the XML file. Before parsing, we call evaluate() a few times. If we evaluated a large enough XML file, we saw the error.
Without getting into the details, we avoid this limitation by evaluating smaller chunks of XML at a time. In our project, we were already including smaller XML into larger XML 'reports', and so we were able to perform the evaluation during this recursion.
