Fix BeanInstantiationException when searching for blacklisted entities

[Copilot]

Searching for a blacklisted accession (e.g. GSE112631) surfaced a BeanInstantiationException to the user because DatabaseSearchSource registers results under the abstract BlacklistedEntity.class type, and EntityUrlChooser.entity(Class<T>, Long) blindly called BeanUtils.instantiate() on it. Since getResultObjectUrlSafely only catches UnsupportedEntityUrlException, the error escaped to the UI.

Changes

• EntityUrlBuilder.EntityUrlChooser.entity(Class<T>, Long) — guard against abstract types upfront with Modifier.isAbstract(), throwing UnsupportedEntityUrlException instead of letting BeanUtils.instantiate blow up:

if ( Modifier.isAbstract( entityType.getModifiers() ) ) {
    throw new UnsupportedEntityUrlException(
        "Cannot generate a URL for abstract entity type " + entityType.getSimpleName() + ".", entityType );
}

• EntityUrlBuilderTest — adds testAbstractEntityType() covering this path with BlacklistedEntity.class.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• maven2.pavlab.msl.ubc.ca
  • Triggering command: /usr/lib/jvm/temurin-17-jdk-amd64/bin/java /usr/lib/jvm/temurin-17-jdk-amd64/bin/java --enable-native-access=ALL-UNNAMED -classpath /usr/share/apache-maven-3.9.14/boot/plexus-classworlds-2.9.0.jar -Dclassworlds.conf=/usr/share/apache-maven-3.9.14/bin/m2.conf -Dmaven.home=/usr/share/apache-maven-3.9.14 -Dlibrary.jansi.path=/usr/share/apache-maven-3.9.14/lib/jansi-native -Dmaven.multiModuleProjectDirectory=/home/REDACTED/work/Gemma/Gemma org.codehaus.plexus.classworlds.launcher.Launcher -pl gemma-core test -Dtest=EntityUrlBuilderTest -q (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
