Hi,
I am migrating from very old version of Ebean 2.8.1 which stops work in Java 11 to the newest version 13.9.3. The previous version does not need enhancer to work. The new one requires it and I have some problems with configuration and I didn't find a sufficient info in documentation.
For now I'm trying to run application in Eclipse and I configured javaagent as described in doc. I have two problems:
1. How to configure enhancer to enhance only specific class (or packages)? For now it seems that it tries to enhance many other classes (everything?!) and it causes errors like:
ebean-enhance> cls: com/sample/SomeClass msg: defaulted common supertype for type1:com/otherpackage/AnotherClassl type2:java/lang/Object due to err:java.lang.IllegalArgumentException: java.io.IOException: Class not found
I found some info about configuration in "ebean.mf" (but no in documentation) and trying to add such file to META-INF, but it does not changed anything.
2. For classes which define entities I receive exceptions:
Error in deployment

Just an interesting note: I was able to run a sample application with Ebean 2.7.4 on Java 11 after adding "javax.xml.bind:jaxb-api" to dependencies:
INFO: Ebean Version[2.7.4] Java Version[11.0.16]
Without that dependency I got the following in the log:
23:07:59,832 ERROR ~ Failed to create ebean server (javax/xml/bind/annotation/XmlRootElement)
But for my real application I got java.lang.ArrayIndexOutOfBoundsException:

So I have to walk through that Ebean upgrade way too! :)

This trace is very similar to the one in my thread. Rob answered that in detail in ebean-orm/ebean#2689.

Hi Szabolcs,
Thanks for your answer.
For Ebean 2.8.1 on Java 11 I have the ClassFormatError:

I haven't found a solution yet. It doesn't work for me, maybe because of multi-module environment (OSGi).
