Unable to start properly after packaging with graalvm

[king-from]

When using multiple data source configurations in JPA, GraalVM was successfully packaged but could not run properly. However, it ran normally in the jar package ![Uploading 20240617155532.png…]()

Please do no upload images but rather use proper GH markup. If you would like us to spend some time helping you to diagnose the problem, please spend some time describing it. Right now, we struggle to understand what you want to achieve. Ideally take the time to provide a complete minimal sample (something that we can unzip or git clone, build, and deploy) that reproduces the problem.

The operation is as follows: Configure multiple data sources through @ Configuration @ Enabling Transaction Management @ Enabling JpaRepositories. After packaging the grailvm, the jar package runs normally, but the executable file runs with an error as follows: [ROOT] appears to have started a thread named [HikariPool-1 housekeeper] but has failed to stop it. This is very similar to creating a memory leak Stack trace of thread: Org. galalvm. nativeimage. builder/com. oracle. svm. core. windows. headers. SynchAPI. WaitForSingleObject (SynchAPI.
