I don't know how much interdependency there is between the `java.compiler` system property and the `java.lang.Compiler` class. On the library side I think they're independent. But it sounds like @dholmes-ora thinks they should be resolved at the same time, so maybe there some things going on between them inside the JVM. The `java.compiler` property still seems to have some actual effect (see src/hotspot/share/runtime/arguments.cpp) so it shouldn't be removed immediately. Instead, it needs to be deprecated and its use should cause a warning to be issued. A comment in that file also mentions `-Xdebug`. The Hotspot help message for that says -Xdebug does nothing. Provided for backward compatibility. which doesn't appear to be true, as `-Xdebug` seems to have an effect on the interpretation of the `java.compiler` property! Ugh. Well, this appears to be the only effect of `-Xdebug`, so maybe the eventual removal of the `java.compiler` property will make the help message become true. Anyway it sounds to me like the next step is to deprecate the `java.compiler` property and to have setting it cause a warning to be issued. If @dholmes-ora thinks that removal of `java.lang.Compiler` should wait until after that, I'm ok with it. P.S. I note that I am finally getting back to @dholmes-ora on this issue, and it is in fact after he has returned from vacation on the 22nd. :-) ------------- PR Comment: https://git.openjdk.org/jdk/pull/13092#issuecomment-1476662136
