--- Comment #5 from Axel Howind <a...@dua3.com> --- I think you actually do need a Java 9 compiler (for the module info), even when a java 8 compiler is used for the rest. So yes, you technically need a java 9 compiler to build even if the resulting jar will be java 8 compatible. We could probably facilitate this! Using a toolchains for the java 9 part too , but at least for the next major release I think we should actually think about finally dropping Java 8 support, and we could even think about requiring at least 17 IMHO. -- 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
