Hi Maxim,
I found the same problem reported in JDK-8299435
<https://bugs.openjdk.org/browse/JDK-8299435> but it was occurring in
Github actions and we never got further information.
The line
An exception has occurred in the compiler (10-internal)
has me wondering where you get your bootstrap JDK from? Perhaps upgrade
that to an earlier JDK 11 version.

Hi,
In GNU Guix, we still have a use for OpenJDK 11 for our source bootstrap
of the latest OpenJDK.
Unfortunately, the build fails non-deterministically with a
ConcurrentModificationException error. This does not seem to occur in
other versions, either the previous 10.46 version or the following 12.33
one. The crash happens early during build, whether using multiple
cores/threads or not, with a backtrace like:

I presume the issue must have been fixed in a later version, but looking
at the git history around the place of the crash doesn't reveal any
obvious fixes that came later. If someone has a suggestion of what to
look into or knows a commit that could have resolved this bug in later
version, please let me know!
