* LUCENE-10185: pass --release 11 to ECJ linter, fix JDK 17 build Otherwise, new java releases such as JDK 18, JDK 19, ... may have even more new deprecations, the build shouldn't fail in such cases. Remove -source/-target now that we pass --release Fix casting so ECJ understands it and creates correct call signature (UweSays: "It's ok. I know why it happens, but it's a bug in ECJ. The type safety is checked by the invokeexact") Co-authored-by: Uwe Schindler <uschindler@apache.org>
