TC 9 plus Java 11 illegal reflective access during unit tests
Hi there,
FYI: during unit tests run (testing tcnative) for TC trunk I get the
following warnings when testing with Java 11:
166 x WARNING: Illegal reflective access by
org.apache.catalina.loader.WebappClassLoaderBase
(file:/.../output/classes/) to field
java.io.ObjectStreamClass$Caches.localDescs
6 x WARNING: Illegal reflective access by
net.sf.cglib.core.ReflectUtils$2
(file:/.../cglib-2.2.2/cglib-nodep-2.2.2.jar) to method
java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int,java.security.ProtectionDomain)
1 x WARNING: Illegal reflective access by
org.apache.catalina.loader.WebappClassLoaderBase
(file:/.../output/classes/) to field java.lang.Thread.target
1 x WARNING: Illegal reflective access by
org.apache.catalina.loader.WebappClassLoaderBase
(file:/.../output/classes/) to field
java.util.TimerThread.newTasksMayBeScheduled
in combination with
WARNING: An illegal reflective access operation has occurred
WARNING: Please consider reporting this to the maintainers of ...
WARNING: Use --illegal-access=warn to enable warnings of further illegal
reflective access operations
WARNING: All illegal access operations will be denied in a future release
Probably know to you and maybe not something to worry right now, but I
don't know for which future version "will be denied in a future release"
will become true.
Regards,
Rainer

Yes, these results are expected. It might be worth starting a discussion
with the OpenJDK folks about alternative APIs for these.
