             Summary: Null pointer exception using the "Entity Classes from Database" wizard
                 Key: NETBEANS-5127
                 URL: https://issues.apache.org/jira/browse/NETBEANS-5127
             Project: NetBeans
          Issue Type: Bug
          Components: javaee - Persistence
    Affects Versions: 12.2
         Environment: Windows 10; Product Version: Apache NetBeans IDE 12.2
Java: 15; OpenJDK 64-Bit Server VM 15+36-1562
Derby DB v10.14.2.0
Wildfly 21.0.1
            Reporter: Stephen Brooksbank


I'm getting a null pointer exception when trying to generate database entity classes using the wizard:

{{java.lang.NullPointerException: Cannot invoke "com.sun.tools.javac.processing.JavacProcessingEnvironment$DiscoveredProcessors.iterator()" because "this.discoveredProcs" is null}}

I'm using Apache Derby DB and Wildfly.There are two unmapped entities in the database (one-to-many relationship), and the persistence context is set up to use JTA.

What gets generated is two "stub" java class files containing only the basic class definition without any content

{{package com.brooksbank.weldexamples.db;}}

{{/**}}
{{ * @author sjbro}}
{{ */}}
{{public class Codetypes {}}

{{}}}

The persistance context is :

{{<?xml version="1.0" encoding="UTF-8"?>}}
{{<persistence }}
{{ version="2.2" }}
{{ xmlns="http://xmlns.jcp.org/xml/ns/persistence" }}
{{ xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" }}
{{ xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_2.xsd">}}
{{ <persistence-unit name="com.brooksbank_weldExamples_war_1.0PU" transaction-type="JTA">}}
{{ <provider>org.hibernate.ejb.HibernatePersistence</provider>}}
{{ <jta-data-source>java:/weldExamplesDS</jta-data-source>}}
{{ </persistence-unit>}}
{{</persistence>}}

The datasource is defined in wildfly as:

{{ <datasource jndi-name="java:/weldExamplesDS" pool-name="weldExamplesDSPool">}}
{{ <connection-url>jdbc:derby://localhost:1527/WeldExamplesDB</connection-url>}}
{{ <driver-class>org.apache.derby.jdbc.ClientDriver</driver-class>}}
{{ <driver>derbyclient.jar</driver>}}
{{ <security>}}
{{ <user-name>******</user-name>}}
{{ <password>******</password>}}
{{ </security>}}
{{ </datasource>}}

The connection to the database works for other database record types and the wizard pulls up the list of entities correctly to select from.
