java.lang.IllegalAccessError: class io.questdb.std.Numbers (in module io.questdb) cannot access class jdk.internal.math.FDBigInteger (in module java.base)

[varunbpatil]

Describe the bug
I have a table with 3855 columns where one column is TIMESTAMP and all others are either INT or DOUBLE.
I am running QuestDB 5.0.1 via docker.
Tried running the following SQL query from both psql as well as UI.

SELECT * FROM test LIMIT 1;

Error in docker logs:

java.lang.IllegalAccessError: class io.questdb.std.Numbers (in module io.questdb) cannot access class jdk.internal.math.FDBigInteger (in module java.base) because module java.base
does not export jdk.internal.math to module io.questdb

To Reproduce
Steps to reproduce the behavior:

1. Run QuestDB docker - docker run --rm -it --net=host questdb/questdb
2. Run psql docker - docker run --rm -it postgres psql -h x.x.x.x -p 8812 -U admin -W -d qdb
3. Import a csv file with 3855 columns where one column is TIMESTAMP and all others are either INT or DOUBLE.
4. Run the following SELECT query in psql/UI - qdb=> SELECT * FROM test LIMIT 1;

Expected behavior
Expect to see one row with all 3855 columns.

Environment (please complete the following information):

• Docker version 19.03
• QuestDB version 5.0.1

command line argument is missing in docker entry point, try adding entry point:

### COMMAND REMOVED ###

EDIT (mpsq): I removed the command since it was invalid, please check the next comment for the solution

@varunbpatil

This is happening because our Docker image does not expose certain JDK classes we rely on, this is a bug. We will fix it and deploy a new patch of our Docker image, in the meantime you can run the container with:

docker run --rm -it --net=host questdb/questdb /app/bin/java -m io.questdb/io.questdb.ServerMain --add-exports java.base/jdk.internal.math=io.questdb -d /root/.questdb

Let me know if this fixes the issue.

@mpsq I'm still getting the same error with the above docker command.
Attaching a file with the docker logs (truncated to hide column names).
docker_logs.txt

@varunbpatil My bad, the parameters are in the wrong order, can you try with:

docker run --rm -it --net=host questdb/questdb /app/bin/java --add-exports java.base/jdk.internal.math=io.questdb -m io.questdb/io.questdb.ServerMain -d /root/.questdb

Instead ;)
