Rebecca Searls created CXF-7894:
-----------------------------------
Summary: ReflectionUtil, JDK-9+ warnings for illegal reflective
access operation
Key: CXF-7894
URL: https://issues.apache.org/jira/browse/CXF-7894
Project: CXF
Issue Type: Improvement
Components: Core
Reporter: Rebecca Searls
Fix For: 3.2.8, 3.2.5
wfly script wsconsume uses CXF. With JDk-9, JDK-10 and JDK-11 the following
warning is always presented.
{code:java}
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by
org.apache.cxf.common.util.ReflectionUtil$11
(jar:file:/home/rsearls/j1/wfly10/wildfly/dist/target/wildfly-15.0.0.Alpha1-SNAPSHOT/modules/system/layers/base/org/apache/cxf/main/cxf-core-3.2.5-jbossorg-1.jar!/)
to field java.net.Authenticator.theAuthenticator
WARNING: Please consider reporting this to the maintainers of
org.apache.cxf.common.util.ReflectionUtil$11
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
{code}
This message can be seen in wfly versions 12, 13, 14, and master with any of the
3 JDK versions listed.
This was a known issue starting with JDK-9. At that time Mark Reinhold
proposed temporary flag, "--illegal-access=permit". The default setting is
"permit". (see,
https://jaxenter.com/jdk-9-replace-permit-illegal-access-134180.html)
The JDK team continues to support this flag in jdk-10 and jdk-11.
Flag option "--illegal-access=debug" prints the warning and a stacktrace for
each illegal reflective access operation.
This flag must be placed in JAVA_OPTS in order for the script to place it
in the correct commend-line position. If this option is placed on the script's
commend-line it is passed to the java class being executed not the java cmd
itself.
Using the "--illegal-access=debug" shows the warnings for line
org.apache.cxf.common.util.ReflectionUtil$11.run(ReflectionUtil.java:194)
{code:java}
public static <T extends AccessibleObject> T setAccessible(final T o) {
return AccessController.doPrivileged(new PrivilegedAction<T>() {
public T run() {
>>> o.setAccessible(true);
return o;
}
});
}
{code}
The stacktrace using the option "--illegal-access=debug" follows.
{code:java}
