Hi Rick,
when cross-compiling for an earlier release you must use the
corresponding class library for that earlier release or use the new
platform flag in JDK 9.
Please see

Hi Rory, Dalibor, Balchandra, and Muneer,
I have gotten the Derby build to work using the javac supplied by b100
of java 9 (referenced below). I have tripped across the following
problem:
If I use the java 9 javac to compile the attached program down to java 8
byte code thusly...
javac -source 1.8 -target 1.8 ByteBufferTest.java
...then the result runs fine under java 9 but fails under java 8 with
the following error message:
Exception in thread "main" java.lang.NoSuchMethodError:
java.nio.ByteBuffer.clear()Ljava/nio/ByteBuffer;
at ByteBufferTest.main(ByteBufferTest.java:9)
Is there something special which I need to do in order to use the java 9
javac to compile programs which will run under java 8?
Thanks,
-Rick
