Description

« Hide

Typing ">" in the RadRails editor for a .rhtml file causes a code assist window to pop up, with entries starting with "a". Then typing a "c" causes the popup to start to reset with entries that start with "c", but the Eclipse program immediately crashes. If I type ">", let the popup appear, then scroll down one line with the mouse (the word "command" appears) all is well. If I try to scroll down one more line, the popup changes for a split second, then Eclipse / Aptana Studio crashes.

I'm using the current versions of the Aptana Studio and the RadRails plugin (0.9.1). I get the same result in both an Aptana/RadRails plugin installed into Eclipse 3.3.1.1, and in Aptana Studio 1.0.2 installed from the file Aptana_Studio_Setup_Linux.zip.

Output of the error dialog that pops up after Aptana crashes:

I've already reported a possibly related bug on ticket ~~ROR-264~~. If it turns out these two should have been together on the same report, I apologize for the duplcation and please merge the two bug reports.

The JVM crash logs indicate problems inside the widget libraries for gtk. My best guess is that perhaps there's just some incompatibility with the beta Java version you're using. Is it possible to try installing a newer Java 6 JRE?

I think these two may be related...

~~ROR-264~~ and this issue are related. I now realize that crash logs from the two report the same "problematic frame":

An unexpected error has been detected by Java Runtime Environment:
#
SIGSEGV (0xb) at pc=0xb4a1c8b6, pid=4719, tid=3084463008
#
Java VM: Java HotSpot(TM) Client VM (1.6.0_10-ea-b08 mixed mode, sharing linux-x86)
Problematic frame:
C [libpangoft2-1.0.so.0+0x58b6]
#

The jre version I was running was the "latest release" version, downloaded from java.sun.com a couple days ago. I've now installed the "Early Access" version (JDK 6 Update N). I think that's the VM getting run, anyway 'java -version' reports "1.6.0_10ea" and "build 1.6.0_10-ea-b08". No change in the results with this VM – still crashing at the same two circumstances.

The library where the crash happens is libpangoft2-1.0.0.so.0. On this machine that points to libpangoft2-1.0.so.0.1001.1. I've looked for an update to this library. opensuse.org has newer versions of the pango rpms (and the cairo rpms that they depend on). The newer pango rpm provides libpangoft2-1.0.so.0.1800.2. The website suggests that these rpms are compatible with my version of SUSE, but they don't install cleanly and Aptana won't launch at all when they are installed. I might try installing a newer version of pango from source, but I'm reluctant to risk making this machine unstable (I use it for more than just development work).

Unfortunately this and ~~ROR-264~~ both appear to be JVM crashes related to library incompatibilities with Eclipse. This is at a low level, and not something we'd really be able to control.

You may want to take a look at Eclipse's Bugzilla for possible related bug reports: https://bugs.eclipse.org/bugs/buglist.cgi?quicksearch=libpangoft2-1.0.so

It may also magically disappear when we use Eclipse 3.3 as our base platform for Aptana Studio: STU-680
