My apache-ant-1.10.9 and openjdk11-1.11.0.10.9 under
NetBSD/amd64-current works for test suites from
https://github.com/AdoptOpenJDK/openjdk-systemtest .

However it requires two patches to start the tests at least.
And some tests fail under NetBSD/amd64-current.
It seems that the other tests require more patches to start or finish the tests.
And Some tests failed with class file version mismatches.
I have no idea about how to fix these mismatches.

Anyway simple build.xml outside pkgsrc works with apache-ant-1.10.9
for me. It is installed as /usr/pkg/bin/ant.

I think that your /opt/local/bin/ant shell script has bad ANT_HOME
and ANT_LIB variables.

Could you send me your /opt/local/bin/ant shell script file?

Thank you.

P.S.
I do not find any difference in their behavior under
NetBSD/amd64-current between openjdk8 and openjdk11 packages yet.
However apache-tomcat9 does not work with openjdk11.
I wish someone can find the critical difference for apache-tomcat9
under NetBSD/amd64-current.
