Does ECJ support value based classes?

[laeubi]

I just came across JEP 390 and it says:

Within the JDK, the @jdk.internal.ValueBased annotation is used to signal to javac and HotSpot that a class is value-based

So the question would be does ecj batch compiler also support @jdk.internal.ValueBased annotations? So if I would add that to a custom type will it have any influence?

Please have a look at https://github.com/eclipse-jdt/eclipse.jdt.core/blob/master/org.eclipse.jdt.core.tests.compiler/src/org/eclipse/jdt/core/tests/compiler/regression/ValueBasedAnnotationTests.java

I can't vouch for the support being complete, so have a look at the tests and/or make your own experiments.
