We are using net.tascalate.javaflow maven plugin to enhance byte code, till jdk8 it is working fine and the build is successful. Once we have upgraded the compiler to java 11 version we are getting the below error when running the maven install.
This is the error that was thrown when trying to install the maven project

I have tried reverting the versions of the artifacts net.tascalate.javaflow.api to 2.6.0, net.tascalate.javaflow.tools.maven to 2.4.1 but still there is same issue.
But when I changed the maven compiler level to jdk 8 the project is building successfully.
Any help would be appreciated.
