When you try to start `11.0.3` via: ``` new Tomcat(); ```An error is thrown: ``` Exception in thread "main" java.lang.ExceptionInInitializerError at TomcatReproducer.main(TomcatReproducer.java:6) Caused by: java.lang.reflect.InaccessibleObjectException: Unable to make field static final boolean java.io.FileSystem.useCanonCaches accessible: module java.base does not "opens java.io <http://java.io/>" to unnamed module @5a4041cc at java.base/java.lang.reflect.AccessibleObject.checkCanSetAccessible(AccessibleObject.java:354) at java.base/java.lang.reflect.AccessibleObject.checkCanSetAccessible(AccessibleObject.java:297) at java.base/java.lang.reflect.Field.checkCanSetAccessible(Field.java:178) at java.base/java.lang.reflect.Field.setAccessible(Field.java:172) at org.apache.tomcat.util.compat.JreCompat.<clinit>(JreCompat.java:87) ... 1 more ``` And Tomcat fails to start. This does _not_ affect `11.0.2` and appears to be introduced in https://github.com/apache/tomcat/commit/bda730151a77a959e851104fe35e8c40ae6045d5. `org.apache.tomcat.util.compat.JreCompat` tries to make `java.io.FileSystem.useCanonCaches` accessible via reflection, which fails due to module accessibility. There is a `catch` for `ReflectiveOperationException` & `IllegalArgumentException`, but `InaccessibleObjectException` is neither of those. You can _probably_ workaround the issue by adding an `--add-opens` VM argument but this isn’t ideal, especially for a patch release.
