--- Comment #2 from Dominik Stadler <dominik.stad...@gmx.at> --- Similar to bug 61572, this one also is caused by reflection usage and only causes an output to stderr as far as I see. Some of these reflection usages are needed in 3.x to allow to run/compile against Java 6, 7 and 8 as some internal JDK functionality is different across versions. So let's first investigate if we can get rid of reflection here after we moved to Java 8 in 4.0 and if we may keep the warning in for 3.17. See https://stackoverflow.com/questions/46230413/jdk9-an-illegal-reflective-access-operation-has-occurred-org-python-core-pysys for some more related description. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@poi.apache.org For additional commands, e-mail: dev-h...@poi.apache.org
