Beschreibung

Describe the bug
A Java program will not work if another Java program uses ObjectBox.

Basic info:

  • ObjectBox version: 3.2.1
  • Reproducibility: always
  • Device: Desktop Java
  • OS: Windows 10, Windows 11 & Linux

To Reproduce
See the Is there anything special about your app?.

Probable way to reproduce the behaviour without using Spigot plugins:

  1. Create two projects that use ObjectBox and place them in the same folder.
  2. Execute each application
  3. See error

Way to reproduce the behaviour USING Spigot plugins:

  1. Create two Spigot plugins that use ObjectBox.
  2. Place the plugins under the \plugins folder.
  3. Start the server & see the error for one plugin.

Expected behavior
ObjectBox should be able to use different .dll files in order for this error not to happen. This could be worked around by providing a method to specify the location of the .dll file, https://github.com/objectbox/objectbox-java/issues/973

Additional context

  • Is there anything special about your app?
    I'm using ObjectBox for Spigot Java plugins. In this context, the objectbox-jni-windows-x64 is being shared for all the plugins that use ObjectBox, and as far as I'm aware, there is no viable way to modify the location of the objectbox-jni-windows-x64 file for each instance. Possibly related with https://github.com/objectbox/objectbox-java/issues/973
    The Spigot standalone loads each plugin and when two plugins are using ObjectBox, the error occurrs.

  4. Öffne einen Pull Request, der die Issue-Nummer nennt.

Rechercherichtung

Beginne mit io.objectbox.internal.NativeLibraryLoader.checkUnpackLib in Zeile 227 und dem zugehörigen Issue #973 und reproduziere anschließend zwei ObjectBox-Anwendungen oder Spigot-Plugins, die die native Bibliothek unter Windows und Linux gemeinsam verwenden. Als erledigt gilt die Aufgabe, wenn beide Benutzer ObjectBox initialisieren können, ohne dass LinkageError oder FileNotFoundException auftreten, während ihre nativen Bibliotheken gleichzeitig geladen werden.
