O Netbeans acha que deve usar o java 8.1, mas você só precisa reinstalá-lo para poder ver a versão correta do java
Netbeans, javac e Java estavam funcionando bem até que eu instalei o Java 9. Agora:
thufir@doge:~$
thufir@doge:~$ sudo update-java-alternatives --list
java-1.8.0-openjdk-amd64 1081 /usr/lib/jvm/java-1.8.0-openjdk-amd64
java-8-oracle 1081 /usr/lib/jvm/java-8-oracle
java-9-oracle 1091 /usr/lib/jvm/java-9-oracle
thufir@doge:~$
thufir@doge:~$ sudo update-alternatives --config java
There are 3 choices for the alternative java (providing /usr/bin/java).
Selection Path Priority Status
------------------------------------------------------------
0 /usr/lib/jvm/java-9-oracle/bin/java 1091 auto mode
1 /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java 1081 manual mode
* 2 /usr/lib/jvm/java-8-oracle/jre/bin/java 1081 manual mode
3 /usr/lib/jvm/java-9-oracle/bin/java 1091 manual mode
Press <enter> to keep the current choice[*], or type selection number: 2

Por que o netbeans está falhando? Tentei remover e reinstalar o IDE. Versões:
thufir@doge:~$
thufir@doge:~$ apt-get -s install netbeans
NOTE: This is only a simulation!
apt-get needs root privileges for real execution.
Also keep in mind that locking is deactivated,
so don't depend on the relevance to the real current situation!
