There are lots of legacy applications still using Java 8. ShardingSphere-JDBC is a java lib, not standalone process, the LTS of Java 8 is necessary.
But there are 200+ modules in ShardingSphere, so I am afraid nobody can undertake the costs of maintain 2 different versions. ------------------ Sincerely, Liang Zhang (John) Apache ShardingSphere 吴伟杰 <wuwei...@apache.org> 于2023年1月12日周四 10:57写道： > I also want to use the Java 11 or 17. > We have had to do some special handling in codes to avoid performance > issues in Java 8 (such as JDK-8161372 [1]). > > [1] https://bugs.openjdk.java.net/browse/JDK-8161372 > > Regards, > Weijie > ----------------------------------------------- > > Wu Weijie 吴伟杰 > Apache ShardingSphere PMC > GitHub@TeslaCN > > Zheng Feng <zhf...@apache.org> 于2023年1月11日周三 20:18写道： > > > > > Hi all, > > > > This thought is coming from upgrading antlr to 4.10.1 [1] which is only > for > > Java 11 now.
