Sergey Ushakov commented on MOJO-1667:
--------------------------------------
Plugin just need to update version, after bug gets fixed in com.intellij:javac2
dependency.
> Code generation injects method $$$setupUI$$$ in wrong place in constructor
> --------------------------------------------------------------------------

> Key: MOJO-1667
> URL: http://jira.codehaus.org/browse/MOJO-1667
> Project: Mojo
> Issue Type: Bug
> Components: ideauidesigner
> Reporter: Sergey Ushakov
> Attachments: uidesignerbug.tar.bz2

>
> When plugin compiles form it injects call to method $$$setupUI$$$ to wrong
> place and splits first instruction in constructor in parts.
> Source code for form:
> {code}
> public class Form {
> private JLabel label;
> Object object;
> public Form() {
> object.toString();
> }
> public static void main(String[] args) {
> try {
> new Form();
> System.err.println("Test passed");
> } catch (NullPointerException e) {
> System.err.println("Test failed");
> System.exit(1);
> }
> }
> private void createUIComponents() {
> object = new Object();
> label = new JLabel();
> }
> }
> {code}
> In this code, field "object" gets initialized in createUIComponents(), that
> is known to be executed in $$$setupUI$$$.
> Part of decompiled class-file, obtained from {monospace}javap -private -s -c
> Form{monospace}
> {quote}
> Compiled from "Form.java"
> public class uidesignerbug.Form extends java.lang.Object{
> private javax.swing.JLabel label;
> Signature: Ljavax/swing/JLabel;
> java.lang.Object object;
> Signature: Ljava/lang/Object;
> public uidesignerbug.Form();
> Signature: ()V
> Code:
> 0: aload_0
> 1: invokespecial #13; //Method java/lang/Object."<init>":()V
> 4: aload_0
> 5: getfield #15; //Field object:Ljava/lang/Object;
> 8: aload_0
> 9: invokespecial #18; //Method $$$setupUI$$$:()V
> 12: invokevirtual #22; //Method
> java/lang/Object.toString:()Ljava/lang/String;
> 15: pop
> 16: return
> {quote}
> Note, code line 9 with call to $$$setupUI$$$ is located in wrong place. It
> should occur before line 4, pushing reference to uninitialized field.
> IDEA version 10.* and 9.* also affected with bug. Related bug at JetBrains
> issue tracker: http://youtrack.jetbrains.net/issue/IDEA-67765
> Maven project with test and decompilation result attached.
