Observed/actual behavior
Bug Report: Conflict between Ledger and QuickBackupM Reforged (Exposed dependency / ClassLoader issue)
Environment
- Minecraft: 26.1.2
- Fabric Loader: 0.19.3
- Java: 25
- OS: Windows Server 2022
- QuickBackupM Reforged: 3.2.7+snapshot
- Ledger: 1.3.20
(Also reproduced by another user on MC 1.21.11 + Ledger 1.3.18 + QuickBackupMulti 3.2.6)
Problem
Server crashes during startup when both Ledger and QuickBackupM Reforged are installed.
Removing Ledger immediately resolves the issue and the server starts normally.
Removing QuickBackupM also resolves the issue.
So the issue appears to be a compatibility/dependency conflict.
Steps to reproduce
- Install Fabric server
- Install QuickBackupM Reforged
- Install Ledger
- Start server
- Wait until world initialization
Actual Result
Server crashes while initializing QuickBackup database.
Crash:
java.lang.NoClassDefFoundError:
org/jetbrains/exposed/sql/Database
at io.github.skydynamic.increment.storage.lib.database.Database.<init>(Database.kt:18)
at io.github.skydynamic.quickbackupmulti.QuickbackupmultiReforged.setNewDataBase()
at DedicatedServer.onLoadLevel()
Root cause:
Caused by:
java.lang.ClassNotFoundException:
org.jetbrains.exposed.sql.Database
Expected Result
Server should start successfully with both mods installed.
Additional Information
Ledger loads:
org_jetbrains_exposed_exposed-core 1.0.0-rc-2
org_jetbrains_exposed_exposed-dao 1.0.0-rc-2
org_jetbrains_exposed_exposed-java-time 1.0.0-rc-2
org_jetbrains_exposed_exposed-jdbc 1.0.0-rc-2
QuickBackupM loads:
incremental-storage-lib 1.3.0
The class:
org.jetbrains.exposed.sql.Database
becomes unavailable at runtime.
Looks like either:
- dependency shading issue
- Exposed version conflict
- Fabric classloader collision
- incremental-storage-lib expects different Exposed package layout
Verified Workaround
Remove:
Server boots successfully.
Changing QuickBackup config does not solve it.
"useInternalDataBase": true
is enough to trigger the crash.
Notes
Another user reported nearly identical stacktrace on:
- MC 1.21.11
- Ledger 1.3.18
- QuickBackupMulti 3.2.6
This may not be specific to Minecraft 26.1.x.

Bug Report: Conflict between Ledger and QuickBackupM Reforged (Exposed dependency / ClassLoader issue)
Environment
(Also reproduced by another user on MC 1.21.11 + Ledger 1.3.18 + QuickBackupMulti 3.2.6)
Problem
Server crashes during startup when both Ledger and QuickBackupM Reforged are installed.
Removing Ledger immediately resolves the issue and the server starts normally.
Removing QuickBackupM also resolves the issue.
So the issue appears to be a compatibility/dependency conflict.
Steps to reproduce
Actual Result
Server crashes while initializing QuickBackup database.
Crash:
Root cause:
Expected Result
Server should start successfully with both mods installed.
Additional Information
Ledger loads:
QuickBackupM loads:
The class:
becomes unavailable at runtime.
Looks like either:
Verified Workaround
Remove:
Server boots successfully.
Changing QuickBackup config does not solve it.
is enough to trigger the crash.
