I suppose so too, but I'd like to see this limitation in Readme. Otherwise "crossplatform" looks kond of misleading ;) ``` $ docker run -it --rm openjdk:alpine sh Unable to...

@khaeru There should some more information about error to be logged out (see [here](https://github.com/iiasa/ixmp_source/blob/master/src/main/java/at/ac/iiasa/ixmp/objects/Scenario.java#L1598)). But it also seems like an issue in the code - it should probably be `checkOut(false);`...

@behnam2015 can you help adding a test for this case or extending one or more of existing? (see test_integration.py and test_core.py for details)

@khaeru sorry for maybe outdated comment on your previous comment: - decoupling is great idea (slightly different though - it could be something like direct (using ixmp jdbc DAO classes)...

@tzipperle to start HSQLDB server you may use following command (same as in your comment): ``` java -cp ../../ixmp/lib/hsqldb.jar org.hsqldb.server.Server --database.0 file:ixmptest --dbname.0 ixmptest ``` To check you can connect...

@tzipperle please ensure the `hsqldb.jar` file exists in the folder at specified path `../../ixmp/lib/hsqldb.jar` - you may need to change path. If you want to try postgresql option - options...

As far as I see `removeSolution` has nothing to do with timeseries. It removes variables and equations (see [at.ac.iiasa.ixmp.objects.Scenario#removeSolution](https://github.com/iiasa/ixmp_source/blob/master/src/main/java/at/ac/iiasa/ixmp/objects/Scenario.java#L1263))

Quickly searching through the code showed that we use float type: - returning variable/equation level/marginal (getLevels, getMarginals) - returning parameter value (getValues) In all other places we use Double.
