> Please review this one liner patch that is fixing a crash in javac when compiling with option `-Xjcov`. The crash was due to an assertion failure at `com.sun.tools.javac.jvm.CRTable` as no position was found for compiler generated `yield` trees in some cases. The fix is to visit the `value` expression in the `yield` tree so that when the CRT table is being generated, the position for the `yield` tree is not `null`

Looks OK to me
