Description GinjaNinja32 2013-10-12 21:33:34 UTC 
Using a method declaration with a 'void' parameter is not marked as an error or warning in the editor, though it will crash the JVM when loaded. Compiling from command-line javac returns no errors, but the resulting class file crashes the JVM with the same error as from within NetBeans.

Example - this code crashes the JVM on load even though none of it is executed:

public class C {
    void m(void v) {}
}

Error:
ClassFormatError: Method [...] has illegal signature "(V)V"

FWIW, I have filled a bug against javac:
https://bugs.openjdk.java.net/browse/JDK-8026374

This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue.

Thanks for your cooperation,
