I installed Netbeans 18 yesterday after using Netbeans 8 for years, and
I get this when opening maven projects:
java.lang.IllegalArgumentException: Key contains code point U+0000

I understand that the cause isn't in Netbeans itself. After looking at
https://github.com/apache/netbeans/blame/35a02e1bec7b6c4b4df51429841bda86b6d1eaf3/java/maven/src/org/netbeans/modules/maven/queries/MavenFileOwnerQueryImpl.java
and seeing that this was (sortof) recently fixed, I've then downloaded
the latest development version.
NetBeans-dev-dev-35a02e1bec7b6c4b4df51429841bda86b6d1eaf3-release.zip on
17.8.2023
Now I get:
WARNING [org.netbeans.modules.maven.queries.MavenFileOwnerQueryImpl]:
Invalid prefrences key at /org/netbeans/modules/maven/externalOwners,
msg: Key contains code point U+0000
So the bad file is in netbeans itself and is named
"externalOwners.properties". Where can I find it? Do I miss some useful
setting when this is skipped? Is this file possibly part of the Netbeans
distribution?
There is a line in netbeans.import with this:
include
config/(Preferences/org/netbeans/modules/maven([.]properties|/(?!externalOwners[.]properties).*)|Projects/org-netbeans-modules-maven/nbactions[.]xml)
