We come to the conclusion that fileds for tables and columns of the target
class must be public, and those not for tables and columns must not be public,
are we right?

In our use case, the Java class which opens calcite connection is contained in
a external Java jar file, which is loaded dynamicly through classloaders other
than the default systemloader like this:
try {
ClassLoader loader = URLClassLoader.newInstance(
new
And if we remove calcite from our project, janino is not in "resolved
depencies" library list of pom.xml,
So we think it not the janino conflic problem.

can you share the solution for the problem, we are using the following
libraries, and it seems janino 3.1.6 is only dependent by calcite-core.

Yes, It is a dependency issue. I have met the same problem. +1 for Dmitry.

I mean it seems not a janino related problem, if we put the connection opening

appear, but with a sql related problem with I sent in another mail.

we use maven and the effective pom contains only the 3.1.0 version of janino as
following:
Actually, I had the same problem with spark. Spark 3.2.1 uses the old
version of janino, calcite 1.29 uses the new version of janino and they are
not compatible.
If I downgrade janino version to version which spark uses I got an error
not method found exception
If I upgrade the janino version to
for example on a current calcite branch:
grep janino gradle.properties
janino.version=3.1.6
yes, we use drools in the same project, and drools uses janino
too, is there a version list of janino which calcite supports?

Hi everyone!
I published a PR https://github.com/apache/calcite/pull/2718
concerning the following Jira issue:
https://issues.apache.org/jira/browse/CALCITE-5008
Could please someone review the PR? The CI seems to be ok with it.
If I'm not doing the correct thing requesting a review here,
Hi!
It looks like a dependency issue, not like a multi-threading issue. Most
likely you have some dependency that use another version of janino but
calcite requires another one

Hi,
we open a calcite connection with ReflectiveSchema in one thread, and execute
sqls in other threads against the connection, but failed with this error

Hey,
I think the main problem is still the lack of active committers/reviewers
and not so much the assignment.
Totally agree - I think this is the core of the problem; the assign-by-files
could somewhat help pulling in the right people - but will not make the job
done.
We could opt for

Hello everyone,
@Vladimir, +1 on the change introducing "enforceDerive()".
@Roman, could you walk us through the limitations you found that forced you
to copy-paste the whole class?
Maybe there is some middle ground for your problem(s) too, similar in
spirit to what Vladimir proposed for the
28 matches
