Compiling the same java source code using Java 11 with release="7" generates different byte code for Windows and Linux. This breaks the cross-platform repeatable builds for Apache Tomcat.

A sample project that demonstrates the problem is available at https://github.com/markt-asf/byte-code-differences

The sample project is derived from the Apache Tomcat source code where the issue was first observed.

The problem is not observed with Java 17 and release="7".

The problem is not observed with Java 11 and release="8".

The Tomcat project may be able to work-around this issue by building releases with Java 17.
