Source: plexus-compiler Version: 2.8.2-5 Severity: normal Dear Maintainer,
plexus-compiler currently will default -source and/or -target to 1.7 whenever the following occours: 1) whenever either has not being set 2) whenever either has been set to 1.6 or earlier This patch modifies the detection logic in order to be able to set the '--release' flag when (and only when): - the '--release' is *not* set - AND both -source and -target are being set to a default value - AND the running jvm is jdk9 or newer This prevents errors such as the infamous "Method flip()Ljava/nio/ByteBuffer; does not exist in class java.nio.ByteBuffer" that is caused by building with openjdk-9 with -source set without setting the proper bootclasspath [1,2]. JEP-247  has provided the --release to prevent such issues and should be used instead of -source whenever the javac being used is jdk9 or higher. I have tested and I can confirm it works fine, but I would like some review to make sure it is sane and get opinions on other (better?) ways to do this - specially concerning the detection of the jvm being run. Also, fork and an alternative javac compiler might be set, thus I would like to discuss as to what behavior it should default it in that case.
