Hi.
I have problem generating Javadoc on JDK 25:
```
netbeans$ JAVA_HOME=/jdk-25/ ant -q -f ide/projectapi javadoc
Trying to override old definition of task javac
Trying to override old definition of task java
Trying to override old definition of task javadoc
Trying to override old definition of task junit
[echo] Build number : 20261001-e3c161964007
Trying to override old definition of task custom-javac
BUILD FAILED
/home/devel/NetBeansProjects/netbeans/nbbuild/templates/projectized.xml:409:
The following error occurred while executing this line:
/home/devel/NetBeansProjects/netbeans/nbbuild/javadoctools/links.xml:229:
JAXP00010004: The accumulated size of entities is "100 001" that
exceeded the "100 000" limit set by "jdk.xml.totalEntitySizeLimit".
```
Just trying: `JAVA_HOME=/jdk-25/ ant
-Djdk.xml.totalEntitySizeLimit=200000 -q -f ide/projectapi javadoc`
doesn't help.
I had to create a special task to `System.setProperty`. What do you
think about such a fix? Shall I create a PR?
