Java 17 crash compiling Oracle JDBC driver code

Issue

• We are seeing recurring crashes in java compiler threads compiling oracle jdbc driver methods like oracle.net.resolver.AddrResolution::resolveAddrTree, oracle.net.resolver.AddrResolution::resolveTNSAddress or oracle.net.resolver.NavAddress::navigate:
