[Bug] Found CDG edge starting at BLOCK node. This is most likely caused by an invalid CFG

[lmfcode]

I am using this warehouse and am prompted with the following error https://github1s.com/JoyChou93/java-sec-code/

` joern> version val res167: String = "2.0.242"

joern> importCode("java-sec-code","sec") Using generator for language: JAVASRC: JavaSrcCpgGenerator Creating project sec for code at java-sec-code Project with name sec already exists - overwriting closing/saving project sec

Invoking CPG generator in a separate process. Note that the new process will consume additional memory. If you are importing a large codebase (and/or running into memory issues), please try the following:

1. exit joern
2. invoke the frontend: /home/ubuntu/bin/joern/joern-cli/javasrc2cpg -J-Xmx968m java-sec-code --output /home/ubuntu/app/code/workspace/sec/cpg.bin.zip
3. start joern, import the cpg: importCpg("path/to/cpg") =======================================================================================================

moving cpg.bin.zip to cpg.bin because it is already a database file Creating working copy of CPG to be safe Loading base CPG from: /home/ubuntu/app/code/workspace/sec/cpg.bin.tmp Code successfully imported. You can now query it using cpg. For an overview of all imported code, type workspace. Adding default overlays to base CPG 2024-02-04 18:20:50.836 WARN CdgPass: Found CDG edge starting at BLOCK node.
