Hi Oracle team, I've just tested JDK 18-ea+23-1525 with Apache Wicket and I've faced the following problem:
[ERROR] Tests run: 29, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.125 s <<< FAILURE! - in org.apache.wicket.util.string.StringsTest [ERROR] org.apache.wicket.util.string.StringsTest.stripJSessionId Time elapsed: 0.011 s <<< ERROR! java.lang.InternalError: java.lang.IllegalAccessException: static final field has no write access: org.apache.wicket.util.string.Strings.SESSION_ID_PARAM/java.lang.String/putStatic, from class java.lang.Object (module java.base) at org.apache.wicket.util.string.StringsTest.stripJSessionId(StringsTest.java:73) Caused by: java.lang.IllegalAccessException: static final field has no write access: org.apache.wicket.util.string.Strings.SESSION_ID_PARAM/java.lang.String/putStatic, from class java.lang.Object (module java.base) at org.apache.wicket.util.string.StringsTest.stripJSessionId(StringsTest.java:73) The related code could be seen at: 1) https://github.com/apache/wicket/blob/d95a3c526229092ecc035ca3e901f5d9a7d4e1c2/wicket-util/src/main/java/org/apache/wicket/util/string/Strings.java#L66 2) https://github.com/apache/wicket/blob/d95a3c526229092ecc035ca3e901f5d9a7d4e1c2/wicket-util/src/test/java/org/apache/wicket/util/string/StringsTest.java#L56-L70 The same code worked with JDK 18 b18 and older versions. I believe the failure is caused by https://github.com/openjdk/jdk/pull/5027 Is this a regression or an intended new behavior and we should update our code ? Regards, Martin
