sherry xu commented on JANINO-133:
----------------------------------

Thanks, Matt! Actually the source code that we sent you might not be a perfect example. We have java classes that have constants less than 65536 and can be compiled using Eclipse or from the command line, but still give us ClassCastException when being compiled with Janino. We can make the error go away by simply shrinking the size of the generated code (with all the constants kept).

> The janino engine failed compiling a java class whose size was 9256 kb (about 140000 lines). A classCastException was thrown as shown in the stacktrace below. Similar errors were received when the source code was downsized to about 95000 lines. The java file compiled with success when it was shrunk to below 60000 lines.
