### Body While loading a project to test the jakartaEE support I noticed this issue: The projects has a parent pom, that is loaded from an internal repository. I configured my `settings.xml`, so that this repository is only added if I run with the corresponding profile loaded. By default the special profile is not loaded and thus the project gets loaded without the right repository present. This situation can be simulated like this: 1. Get the reproducer code: [reproduzer.zip](https://github.com/apache/netbeans/files/12006313/reproduzer.zip) 2. Unzip it 3. Run `mvn install` from the `demo` repository 4. Simulate, that the artifact comes from a remote repository, that is currently unavailable (this assumes, that you are on a Unix-like System: ``` echo "demo-1.pom>demo=" > $HOME/.m2/repository/demo/demo/1/_remote.repositories` ``` To my understanding this tells the system, that the artifact comes from the repository with id `demo` (I used my problematic artifact as basis for this hypothesis) 5. Build NetBeans `master` from source 6. Run `ant tryme` 7. Open the `brokenmavenproject` maven project You can observe on the CLI output: ``` [exec] [Maven project reloading] INFO org.eclipse.aether.internal.impl.DefaultArtifactResolver - Artifact demo:demo:pom:1 is present in the local repository, but cached from a remote repository ID that is unavailable in current build context, verifying that is downloadable from [central (https://repo.maven.apache.org/maven2, default, releases)] ``` The UI becomes unresponsive, CPU usage as reported by VisualVM is around 10%, with spikes to 30%, heap usage is steadily growing. The Threaddump also seems to lead to maven. <details> <summary>Threaddump</summary> ``` 2023-07-10 22:38:33 Full thread dump OpenJDK 64-Bit Server VM (11.0.18+10-LTS mixed mode): Threads class SMR info: _java_thread_list=0x00007fa1ec075cf0, length=43, elements={ 0x00007fa324334800, 0x00007fa324338800, 0x00007fa32434e800, 0x00007fa324350800, 0x00007fa324352800, 0x00007fa324355000, 0x00007fa324357000, 0x00007fa324432800, 0x00007fa324509800, 0x00007fa324898000, 0x00007fa32492a800, 0x00007fa298068000, 0x00007fa298124800, 0x00007fa29803e800, 0x00007fa298198800, 0x00007fa29819a000, 0x00007fa298d6b000, 0x00007fa2995ca800, 0x00007fa299d99000, 0x00007fa298cf6800, 0x00007fa298a54800, 0x00007fa299394000, 0x00007fa299395000, 0x00007fa29ab46800, 0x00007fa298958800, 0x00007fa22857d800, 0x00007fa2282e0800, 0x00007fa298eed800, 0x00007fa298607000, 0x00007fa298ecd800, 0x00007fa29ab20800, 0x00007fa268ab5000, 0x00007fa32402e800, 0x00007fa299153800, 0x00007fa20c015000, 0x00007fa290008800, 0x00007fa29000a800, 0x00007fa2cc001000, 0x00007fa2b0037800, 0x00007fa2b480c800, 0x00007fa2ac162800, 0x00007fa2ac164000, 0x00007fa2b4893000 } _to_delete_list=0x00007fa2241f0230, length=44, elements={ 0x00007fa324334800, 0x00007fa324338800, 0x00007fa32434e800, 0x00007fa324350800, 0x00007fa324352800, 0x00007fa324355000, 0x00007fa324357000, 0x00007fa324432800, 0x00007fa324509800, 0x00007fa324898000, 0x00007fa32492a800, 0x00007fa298068000, 0x00007fa298124800, 0x00007fa29803e800, 0x00007fa298198800, 0x00007fa29819a000, 0x00007fa298d6b000, 0x00007fa2995ca800, 0x00007fa299d99000, 0x00007fa298cf6800, 0x00007fa298a54800, 0x00007fa299394000, 0x00007fa299395000, 0x00007fa29ab46800, 0x00007fa298958800, 0x00007fa22857d800, 0x00007fa2282e0800, 0x00007fa298eed800, 0x00007fa298607000, 0x00007fa298ecd800, 0x00007fa29ab20800, 0x00007fa268ab5000, 0x00007fa32402e800, 0x00007fa299153800, 0x00007fa20c015000, 0x00007fa290008800, 0x00007fa29000a800, 0x00007fa2cc001000, 0x00007fa2b0037800, 0x00007fa2b480c800, 0x00007fa2ac162800, 0x00007fa2ac164000, 0x00007fa2b4893000, 0x00007fa2245e1800 } "Reference Handler" #2 daemon prio=10 os_prio=0 cpu=38,69ms elapsed=200,54s tid=0x00007fa324334800 nid=0x15a45d waiting on condition [0x00007fa2f4919000] java.lang.Thread.State: RUNNABLE at java.lang.ref.Reference.waitForReferencePendingList([email protected]/Native Method) at java.lang.ref.Reference.processPendingReferences([email protected]/Reference.java:241) at java.lang.ref.Reference$ReferenceHandler.run([email protected]/Reference.java:213) Locked ownable synchronizers: -

The problem is reproducible with the commit and not without it. As verifier I build master, reproduced the problem and reverted ad99e85b260eb029462b4c3ae2cef022b1541b61 and could not reproduce it anymore. @sdedic could you please have a look at this? Could there be a loop, that causes, the "broken" project to load in a loop and explain this problem? ### Committer - [X] I acknowledge that I am a maintainer/committer in the Apache NetBeans project. -- This is an automated message from the Apache Git Service.
