#19 Invalid input exception

Brian Brooks — Tue, 19 Jul 2016 19:24:30 -0000

I encountered the same defect with Eclipse Mars SP2 (eclipse.buildId=4.5.2.M20160212-1500)...
metrics plugin version 1.3.8.20100730-001
java version "1.8.0_66"

fields referenced through 'this' ignored

Tony Edgin — Wed, 28 Dec 2011 23:37:53 -0000

I just noticed that the fields referenced through the this pointer are ignored in the Henderson-Sellers lack of cohesion measure.

For instance.

this.aField; // ignored
aField; // not ignored

Error prevents Histograms and Dashboard output

Anonymous — Fri, 08 Jul 2011 14:21:48 -0000

When generating HTML output with Histograms and Dashboard selected, I see the following error message:

"Found class com.sun.image.codec.jpeg.JPEGImageEncoder, but interface was expected"

and no output is generated.

Angle brackets appear in method name

Anonymous — Fri, 08 Jul 2011 13:31:11 -0000

The code I'm analysing includes the following static initializer block:

static {
try {
exportStaticMethods();
} catch (Exception ex) {
Log.error(ex.getMessage(), ex);
}
}

This results in the following line in the XML output:

The angle brackets in the name are not valid XML (according to Firefox), so the file has to be edited before use.

incorrect number of classes/types reported

Radu Vanciu — Sat, 04 Jun 2011 22:36:00 -0000

I used metrics for getting the metrics of ATMExample, and the number of classes reported in Summary Statistics is 57. However, 65 class files are generated when the project is compiled. Also, the file types.csv reports 67 types.

I found the following duplications in types.csv:

PACKAGE TYPE LINE
banking Receipt$(anonymous) 59
banking Receipt$1 59
simulation SimulatedBank$Failure 236
simulation SimulatedBank.Failure 236

The source code of ATMExample is available here: http://www.cs.gordon.edu/local/courses/cs211/atmexample.tar

metric computation on full build should run in backgroun

Anonymous — Mon, 23 Aug 2010 14:20:06 -0000

On a large project it takes some time for all metrics to be computed. This appears to be a blocking operation. Is there any reason it can't be offered to run in the background? This is hit, for example, if a metric configuration setting (e.g. a threshold) is changed.

Invalid input exception

Unfortunately the exception doesn't include on which file.

eclipse 3.5.1

Anonymous — Thu, 18 Feb 2010 18:44:54 -0000

hi,
thanks for writing this code! my friend sent me some stats and i think it is really useful, so thanks!

i am running eclipse 3.5.1 on linux and i don't have the 'metrics' option under the project properties (nor under global properties), and as thus, i don't see the metrics in the problems view.

thanks!

Index Out Of Bounds thrown for static blocks

Anonymous — Thu, 22 Oct 2009 13:21:38 -0000

This is the root cause of my 'Index Out of R' defect... By tinkering I have found that the writeMethodInfo method of com.stateofflow.eclipse.metrics.export.csv.RowWriter is throwing an index out of bounds exception for static blocks as these have no method name, or more importantly a '(' to search for. My tinkering has shown the return value of methodInfo.getName() in these cases to be <init>
