How do I bootstrap building the jdk?

Question

I am attempting to build jdk-11+8 in order to read the generated source of java.nio.ByteBuffer for Linux.

I installed all the dependencies based on the documentation, and then successfully ran configure.

However, when I run make, I get a strange error about a missing Java package, which looks like a bootstrapping problem.

git clone https://github.com/openjdk/jdk.git 
pushd jdk
bash configure
...
The existing configuration has been successfully updated in
/home/ubuntu/Code/jdk/build/linux-x86_64-normal-server-release
using default settings.

What am I missing?

Digging a little more, I also see the following error, which may or may not be relevant:

Answer 1

It turns out that I was using JDK 11 as the boot JDK, and this was not working because the javax.annotations package was removed from JDK 11.

Downgrading to jdk 10 manually and pointing configure at it fixed the problem for me.

wget https://download.java.net/java/GA/jdk10/10.0.2/19aef61b38124481863b1413dce1855f/13/openjdk-10.0.2_linux-x64_bin.tar.gz
tar xf openjdk-10.0.2_linux-x64_bin.tar.gz

bash configure --with-boot-jdk=/home/ubuntu/Code/jdk10/jdk-10.0.2
make

Since jdk 10 is deprecated, I had to pull the link from the archive.
