Testing a release candidate for 7.0.97: When I run it with Java 13 (13u0 64-bit from Oracle, running on Windows 10) I see the following messages in the output of Apache Ant: > [junit] WARNING: An illegal reflective access operation has occurred > [junit] WARNING: Illegal reflective access by org.apache.catalina.loader.WebappClassLoaderBase$1 (file:/D:/workspace/temp/temp.2019-10-10_tc7097/apache-tomcat-7.0.97-src/output/classes/) to method java.lang.ClassLoader.registerAsParallelCapable() > [junit] WARNING: Please consider reporting this to the maintainers of org.apache.catalina.loader.WebappClassLoaderBase$1 > [junit] WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations > [junit] WARNING: All illegal access operations will be denied in a future release See bug 63837 and ant_test.log attached to it for the details and the full log output. https://bz.apache.org/bugzilla/attachment.cgi?id=36821 I am marking this issue as an enhancement. It as warning and not a showstopper.
I do not see the warnings when I start Tomcat normally with catalina.bat.
Fixed in: - master for 9.0.28 onwards - 8.5.x for 8.5.48 onwards - 7.0.x for 7.0.98 onwards
