reproducible crash of JDK with NetBeans

I was trying to run a development version of NetBeans on a beta release of Hopper (beta 12). The JVM crashed suddenly. I attached an error report to this message. I also attached a stack trace of an exception that was thrown just before the VM crashed. [hs_err_pid26875.log, exception.log]

The error ID (4F530E43505002E6) is the same as in JDK bug #4683754 ("REGRESSION: JCK1.4: -Xincgc crashes VM in several tests") but I do not use incremental GC.

When I tried to reproduce the crash, I reproduced a crash with the same error ID but with a different error report. [hs_err_pid30565]

I can reproduce the crash by the following steps:

1) Install NetBeans 3.3.1.
2) Start it using JDK 1.4.1-beta-b12, e.g.:

      bin/runide.sh -jdkhome /usr/local/hopper/b12/j2sdk1.4.1

3) In the IDE:
   a) Settings Import Wizards, click "Finish"
   b) In the Setup Wizard, click "Finish".
   c) Close the Welcome window.
   d) In window "Explorer [Filesystems]", right-click on the default
      filesystem (.../sampledir). A pop-up menu will appear.
      Select "New -> GUI Forms -> JPanel".
   e) In the "New Wizard - JPanel", click "Finish"
      (use a default name).
   f) Activate window "Form Editor [MyPanel]".
   g) There is a hierarchy of GUI components displayed in the
      top right corner of the window. Right-click on node "[JPanel]"
      and select "Set Layout -> GridBagLayout" from a pop-up menu.
   h) Put two JLabels to the panel.
      (To put a component to a panel, click on the component's icon
      in the toolbar and then click on the panel.)

      (There should be four subnodes under node [JPanel] in the hierarchy
      of components: GridBagLayout and two JLabels.)

   e) Right-click on node GridBagLayout and select "Customize".
      A customizer dialog appears.
   f) "jLabel1" is selected - marked with four blue squares.
      In the bottom left part of the dialog, there are several panels
      with buttons: "Anchor", "Fill", "I-Padding", "Insets" and
      "Grid Size". In the top part of panel "Insets", there is a group
      of eight buttons [+] and [-].

      (We are now almost finished.)

      Click on the top left button [+] to increase insets of "jLabel1".
      Select "jLabel2".
      Click on the top left button [+] to increase insets of "jLabel2".

      The VM will crash.
