Subject [jira] [Commented] (IVY-1569) Illegal access warnings with Java 9
Date Tue, 28 Nov 2017 16:53:00 GMT

Wouter van Reeven commented on IVY-1569:
----------------------------------------

Thanks very much. One option would be for you to test for the Java version used and use different
code for Java 9 than for older versions. But yes, the WARNING is harmless and we can ignore
it for now.

> When doing an ant ivy:resolve with Java 9, an illegal access warning is logged:
> resolve:
> [ivy:retrieve] :: Apache Ivy 2.3.0 - 20130110142753 :: http://ant.apache.org/ivy/ ::
> [ivy:retrieve] :: loading settings :: file = common/conf/ivysettings.xml
> [ivy:retrieve] :: resolving dependencies :: XXXX
> [ivy:retrieve] 	confs: [compile, runtime, ext]
> WARNING: An illegal reflective access operation has occurred
> WARNING: Illegal reflective access by org.apache.ivy.util.url.IvyAuthenticator (file:common/lib/ivy-2.3.0.jar)
to field java.net.Authenticator.theAuthenticator
> WARNING: Please consider reporting this to the maintainers of org.apache.ivy.util.url.IvyAuthenticator
> 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
> There is a workaround which is to use --add-opens command line options to the invocation
of java but unfortunately this cannot be done when using ivy in Ant. Please revise the code
and fix this . Many thanks in advance!
