Description
Ravishankar K (Oracle)
(In reply to comment #0) > 1. Create 2 SWT Text controls using the SWT.MULTI style Is this inside an Eclipse plug-in or can you reproduce the problem with a regular SWT snippet? Please provide the code to reproduce the problem. Are you using the Motif or GTK+ SWT build? > 3. When you are typing the text in the other control (or if you go out of > focus), eclipse hangs for a while and then crashes without emitting any > messages in the .log file or anything under the eclipse folder Which VM are you using? Are you using HotSpot? Please search your system for hs_err_pid* log files. I am using the GTK+ SWT build. Here's what i am using: bash-3.2$ java -version java version "1.6.0_20-rev" Java(TM) Platform, Standard Edition for Business (build 1.6.0_20-rev-b03) Java HotSpot(TM) Server VM (build 16.3-b02, mixed mode) I cannot reproduce this issue in a standalone SWT snippet. It is failing within an eclipse plugin, specifically when displaying within the peoprty sheet: here's some code: Composite composite = getWidgetFactory().createFlatFormComposite(parent); nameText = controlFactory.createText(composite, SWT.SINGLE); descriptionText = controlFactory.createText(composite, SWT.MULTI | SWT.H_SCROLL | SWT.V_SCROLL | SWT.WRAP); In the code above, i don't have any issues with the nameText but i have issues when i edit and go away from descriptionText. I will try to create a small eclipse plugin and see if i can reproduce this. Created attachment 176199 [details]
gdb command output for the core file

I saw a core file when eclipse crashed. I could not locate the hs_err_id log file. Please let me know if you see anything useful in the file i have attached. Here's the best information i could see in the log file: Thread 1 (process 23356): #0 0xb7faf402 in __kernel_vsyscall () #1 0x00be6040 in raise () from /lib/i686/nosegneg/libc.so.6 #2 0x00be7a21 in abort () from /lib/i686/nosegneg/libc.so.6 #3 0x0037ab32 in g_logv () from /lib/libglib-2.0.so.0 #4 0x0037ab69 in g_log () from /lib/libglib-2.0.so.0 #5 0x0037abe6 in g_assert_warning () from /lib/libglib-2.0.so.0 #6 0x00753c2b in ??

() In the machine where the problem happens, What is the version of gtk ? What is the locale, is there an input method problem running ? Which one ? Is accessibility enabled ? If so, turning it off fixes the problem ? Please, try to find that hs_err_id log file. Thank you GTK version: ============ $ rpm -q gtk2 gtk2-2.10.4-20.el5 Locale: ======= $ locale LANG=en_US.UTF-8 LC_CTYPE="en_US.UTF-8" LC_NUMERIC="en_US.UTF-8" LC_TIME="en_US.UTF-8" LC_COLLATE="en_US.UTF-8" LC_MONETARY="en_US.UTF-8" LC_MESSAGES="en_US.UTF-8" LC_PAPER="en_US.UTF-8" LC_NAME="en_US.UTF-8" LC_ADDRESS="en_US.UTF-8" LC_TELEPHONE="en_US.UTF-8" LC_MEASUREMENT="en_US.UTF-8" LC_IDENTIFICATION="en_US.UTF-8" LC_ALL= In the System->Preferences->Input Method, i see that it's set to "Follow the System-wide configuration [SCIM]" I did a system wide search and i could not locate the hs_err_pid log file. I also see that Accessibility is turned OFF on this System. Can you turn off SCIM ? Does it make a difference ? I turned SCIM off and set it to "Never Use Input Methods" and i still see the problem. As a side note, i noticed that if i use StyledText instead of Text i have no problems. Can you please attach a snippet that I can use to reproduce the crash ? This crash happens when using Text(SWT.MULTI) in the tabbed property sheet only. I don't see an issue if i use Text anywhere else like the editor and dialogs. And on top of it i tried a small plugin which uses the Text Multi in the property sheet and i cannot seem to reproduce the problem. That's been the difficulty in attaching a reproducer. This makes me think that there is some other thing in my product which may be causing this side effect. I understand, but without a reproducible test case and without the log file I don't know how to provide futher help to you. Please let me know of any future information that can help us here. After looking at http://wiki.eclipse.org/IRC_FAQ#Crashers.2C_Freezing.2C_and_other_Major_Issues (bug 215234) Since my machine was indeed using GTK 2.10, I added the following line to my eclipse.ini: -Dorg.eclipse.swt.internal.gtk.disablePrinting and i have no problems now. This flag will work as a workaround for now. Do you see how the flag can affect Text functionality? Also, i am not sure why i could not have the hs_err* log file generated. Should i do anything specific to see this logfile ? I tried passing in the -XX:ErrorFile=<logfilename> and i still don't see the log file. I can't reproduce this crash, and the system this bug happened on isn't supported any longer. |
