Hi Peter:
I believe this is being discussed under bug #JDK-8066761
<https://bugs.openjdk.java.net/browse/JDK-8066761>
*Investigate -sourcepath usage in when compiling java*
<https://bugs.openjdk.java.net/browse/JDK-8066761>
HTH-

I thought I might inform you that recent checkout of JDK9 (with
modular RT images) fails to build with JDK8u25 as bootstrap JDK. With
JDK8u20 it works correctly. Tried on Linux and Windows. The
configuration on Linux is:
Configuration summary:
* Debug level: release
* HS debug level: product
* JDK variant: normal
* JVM variants: server
* OpenJDK target: OS: linux, CPU architecture: x86, address length: 64
Tools summary:
* Boot JDK: java version "1.8.0_25" Java(TM) SE Runtime
Environment (build 1.8.0_25-b17) Java HotSpot(TM) 64-Bit Server VM
(build 25.25-b02, mixed mode) (at /home/peter/Apps64/jdk1.8.0)
* Toolchain: gcc (GNU Compiler Collection)
* C Compiler: Version 4.8.3 (at /usr/bin/gcc)
* C++ Compiler: Version 4.8.3 (at /usr/bin/g++)
Build performance summary:
* Cores to use: 7
* Memory limit: 15757 MB
Here's the build session:

...etc...
It seems that something changed between JDK8u20 and JDK8u25 regarding
bootclasspath handling of javac as the above errors suggest that JDK9
sources are being compiled against JDK8 classes.
