#1112 Scheduling/threading problem in Eclipse 4.2
When attempting to run Findbugs on an Eclipse project I get the following exception. This happens on all projects I've tried, as well as when attempting to run on an individual file.
java.lang.IllegalArgumentException: Attempted to beginRule: P/Application, does not match outer scope rule: MutexSchedulingRule, resource: P/Application

Hi,
I'm sorry for not reacting on the bug for so long time.
I can't reproduce this issue. More strangely, I've seen it by myself once, and looking at the code/stack trace I can't really get any idea why 2!=2 is.
if (baseRule != null && rule != null && !baseRule.contains(rule))
illegalPush(rule, baseRule);
!baseRule.contains(rule)...
(MutexSchedulingRule on project A) ! contains project A
project A ! contains project A
path !isprefixof path
paths are equals here, but why we have false???
why...

Hi,
I've tried to separate jobs - the error shouldn't happen anymore, but I could introduce new problems. Please check if the newest eclipse-daily build is OK for you.
I will be able tp test it in production env. by the end of this week.
See http://code.google.com/p/findbugs/source/detail?r=14435
Regards,
Andrey
I've tested it on the latest daily build (2.0.2.20120910) and had no problems so far (although I've not tested it extensively) - it looks fixed to me, thanks.
FYI the latest daily build (2.0.2.20120928) fixed the issue for Juno Service Release 1, Build id: 20120920-0800.
Thanks for testing, I've also had no issues so far with Eclipse 3.8.
Hi. this seems to be fixed, but I get something really similar:
An internal error occurred during: "Finding bugs in VavDataTest.java...".
Attempted to beginRule: MultiRule[P/ch.xxx.tests.roboelectric,P/.org.eclipse.jdt.core.external.folders], does not match outer scope rule: MutexSchedulingRule, resource: L/ch.xxx.tests.roboelectric/src/ch/xxx/model/impl/vav/VavDataTest.java
My setup:
- Findbugs 2.0.3
- Eclipse JDT 3.8.2 (bundled in Android Developer Tools 22.3.0)
- Eclipse Platform 4.2.1 (bundled in Android Developer Tools 22.3.0)
- Eclipse RCP 4.2.2 (bundled in Android Developer Tools 22.3.0)
The error occurs in a Testproject that has a dependency on another project + a dependency on an external JAR file, referenced through a build path variable.
Any suggestions or an explanation what the error message actually means would be appreciated.
Kaspar, please can you provide stack trace? Thanks,
Andrey
Hi Andrey
yes, sorry I forgot (just returned from Vacation):
