#93 ArrayIndexOutOfBoundsException while Instrumentation

[Marc R. Hoffmann]

Hi Vlad,

EclEmma users report ArrayIndexOutOfBoundsExceptions while instrumenting Code, which has been generated with the Eclipse compiler against Java 1.6. A got at least two different Stack traces (see below), unfortunately I don't have a reproducable test case yet.

EMMA version is 2.0.5312 (with a minor fix in Logger, see bug #1641403).

The corresponding EclEmma bug is:

https://sourceforge.net/tracker/?func=detail&atid=883351&aid=1912359&group_id=177969

Best regards,
-marc

I encountered this issue today after updating to the latest Ubuntu release (Heron). Ubuntu appears to have updated my jdk to 1.6.0.06. I downloaded & installed update 2 instead and the error in Emma went away. This is with emma-2.0.5312.jar.

Sorry. I forgot to mention that I'm running the 64-bit (server) JVM:

java version "1.6.0_02"

face the problem myself, on a application compiled with jdk1.6.0_06, when switching the compilation to use JAVA_HOME=/usr/jdk/1.5.0_09 it all worked fine.

Compiling or not from Eclipse doesn't seems to affect the behaviour.
Though i'm not familiar with Eclipse, may be there are some compilation settings that could enter in account.

i use to have stacktrace :

Is this the same? On Fedora 9, OpenJDK 1.6.0, I get a stacktrace (attached). I'm rather new to emma, and anything is possible. I started with a small project, and emma worked fine. Now, after adding a few more source files, I get the exceptions. I guess the heart is

FIXED - Upgrading to SUN JDK - Java SE 6 Update 10 overcame this problem.

I'm copy and pasting my own experience with EclEMMA, as reported in EclEMMA bug #1912359:

My own experience:
- Eclipse 3.4 64 bit version under Windows XP x64, runned with JRE
1.6.0_05 64-bit, code compiled with 1.5 conformance and runned with a
1.5.0_15 64-bit JRE: this problem does occur
- Eclipse 3.4 64 bit version under Windows XP x64, runned with JRE
1.6.0_05 64-bit, code compiled with 1.5 conformance and runned with a
1.6.0_05 64-bit JRE: this problem does occur
- Eclipse 3.4 64 bit version under Windows XP x64, runned with JRE
1.5.0_15 64-bit, code compiled with 1.5 conformance and runned with a
1.5.0_15 64-bit JRE: this problem does not occur
- Eclipse 3.4 32 bit version under Linux Ubuntu, runned with JRE 1.6.0_06
32-bit, code compiled with 1.5 conformance and runned with a 1.5.0_16
32-bit JRE: this problem does not occur

Please note that when using the 1.6.0_05 JRE for running Eclipse, the
following VM parameters are used, buth under WinXPx64 and Linux:
-XX:CompileCommand=exclude,org/eclipse/core/internal/dtree/DataTreeNode,forwardDeltaWith
-XX:CompileCommand=exclude,org/eclipse/jdt/internal/compiler/lookup/ParameterizedMethodBinding,<init>
because of the HotSpot 10 bug referenced by:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=214092

My suspect, anyway, is that the problem resides in running Eclipse with a
1.6.0 64-bit JRE.

I can confirm this on 1.6.0_06, 1.6.0_07 and the 1.6.0_10 release candidate.

Sometimes (10% of the time? Can't find a way to reproduce) it seems to work, the rest of the time it fails like this.

Given that the last update to this project was over three years ago, I think the odds of it being fixed without one of us giving it a shot are pretty slim.

[Chris stevenson]

This is caused by a synchronization issue in the InstrVisitor. I have a fix and will attach the patch to this issue. If anyone is still mantaining this it would be good to add that.

[Marc R. Hoffmann]

Hi Chris,

yes, please provide the patch. For EclEmma I maintain a version of EMMA with few important patches.

And could you please explain some details about the issue? From my understanding the instrumentation process is a single threaded only.

Best regards,
-marc

[mauromol]

Hi Marc,
I think Skizz's patch is at http://sourceforge.net/tracker/index.php?func=detail&aid=2119913&group_id=108932&atid=651897
(bug number 2119913).

I got the same problem running on macOS.

I'm using EMMA 2.1.5320
