Forward compatibility

Reports Java code constructs that may fail to compile in future Java versions.

The following problems are reported:

• Uses of assert, enum or _ as an identifier

• Uses of the var, yield, or record restricted identifier as a type name

• Unqualified calls to methods named yield

• Modifiers on the requires java.base statement inside of module-info.java

• Redundant semicolons between import statements

Example:

Fixing these issues timely may simplify migration to future Java versions.
