JDK-4908942 - JAVA program hangs with XInitThreads call with JDK1.4, but works with JDK1.3.1
Description
A customer developing their software has reported that their application appears to hang in XinitThreads call on system running JDK 1.4.2_03. This looks very similar to one of the issues described in bug 4908942 and initial investigation seems to suggest that the application hangs in C++ JNI call to XInitThreads(). The program does not exhibit this behaviour with the same system running Solaris 9 plus patches running Java 1.3.1_10.

The problem has been reliably reproduced here on systems running:

  * Solaris 9 (latest patches)
  * java 1.4.2_02
  * C++ 5.5 (latest patches)

The customer explained:

Apparently AWT and swing internally do not call XInitThreads(). If
XInitThreads() is called, AWT or swing contain code that causes a hang.

This is occurring with our customers who try to load our app (MainWin) into a Java based application, and also use AWT/swing


short description of the problem:
This is the stack when java hangs:
  [6] _XLockDisplay
  [7] XFindContext
  [8] _XmGetWidgetExtData
  [9] _XmGetFocusData
  [10] XmGetFocusWidget
  [11] 0xfbdb6a0c
  [12] XCheckIfEvent

java calls XCheckIfEvent, and supplies a callback function. This
callback function causes the call to XFindContext. When our app loads, it calls
XInitThreads (enables X locks, for safe multithreaded execution). As a
result of the X locks initialization, XCheckIfEvent locks the display.
XFindContext fails to lock the already locked display, and hangs.

The customer is using the XInitThreads as described in manpage

EVALUATION Name: rpR10076 Date: 02/13/2004 This bug is related to 4908942. Though having slightly different visible effects, they are caused by the same problems. Unfortunately, the problems are two: one is in J2SE code, and another is in X11 code. So, to resolve this issue completely, we will need not only the changes to J2Se code, but we will need xserver bug 4985837 escalated and fixed for Solaris 8 and Solaris 9. ###@###.### ======================================================================
