It seems a database reaches some state where it freezes upon switching databases.
I don't know what causes this state (I am using simple cypher queries, nothing complicated)... however, I am attaching files to reproduce the error.

To reproduce the error

1. Unzip attached database folders (where 'ea' seems to be in the locked state)
   databases.zip

2. Start ArcadeDB using unzipped databases...e.g. docker command, but replace YOURPATH

docker run -p 2480:2480 -p 2424:2424 --name arcadedb \
    -v /YOURPATH/databases:/home/arcadedb/databases \
    -e JAVA_OPTS="-Darcadedb.server.rootPassword=playwithdata" \
    arcadedata/arcadedb:latest

3. Open ArcadeDB studio...
   Querying 'ea' works fine. However switch to "parts' database, then switch back to 'ea' database... it will freeze/crash with ArrayIndexOutOfBoundsException
