[NETBEANS-576] The FindBugs plugin works with JDK8 but not with JDK10

• Type: Bug
• Status: Open
• Priority: Minor
• Resolution: Unresolved
• Affects Version/s: 9.0
• Component/s: java - FindBugs

Description

[1] I created a trivial Java application with some issues for FindBugs to identify:

package app;

public class App {

static String s1; int j; Boolean b1;

public static void main(String[] args) {
    System.out.println("JRE version: " + System.getProperty("java.version"));
    if (s1 == "abc") {
    }
}

public boolean equals(App i) {

    int j = this.hashCode();
    return this.equals(new App());
}

}

[2] When the application was run it displayed displayed: JRE version: 1.8.0_162. 

[3]Then I ran Source > Inspect... using FindBugs (version 1.32) on the file App.java. FindBugs identified eight issues in the Inspector window, as shown in the attached screen shot FindBugsJDK8.png.

[4]Next I added JDK 10 as a Java platform, and amended the properties of the project as follows:

• Libraries > Java Platform: JDK 10

• Sources > Source/Binary Format: JDK 10

[5]As expected, when the application was run again it displayed: JRE version: 10 

[6] However, when I ran Source > Inspect... using FindBugs on the file App.java again, using code compiled and run with JDK10, there was no FindBugs output in the Inspector window. See the attached screen shot FindBugsJDK10.png.

(My understanding is that FindBugs hasn't been updated for several years. Could NetBeans possibly use its successor, SpotBugs, as a plugin instead?)
