ArrayIndexOutOfBoundsException using content assist #808

Can you share the expression you are trying to complete when this exception occurs? I am not seeing it on the |

I was able to find an extension method which triggers the exception consistently. Note that if I complete the method name like this

What library is |

The source code for this class is not public and the jar is not published on a public mvn repo either. Only alternative would be to download it from our update site and extract it from the plugin jar packing it (after extraction it's in |
|
It looks like My intuition is that the lack of sources is the result of the issue. I'm setting up a small project with only the toro library to test that out. |

Thanks for that info. Could you try two separate things for me?
|

If I remove the javadoc link the error is not showing anymore. |

Okay, here's what is going on. This section of BinaryMethod.getParameterNames() is trying to parse the param names out of the retrieved javadoc string (included below). if (methodDoc != null) {
int indexOfOpenParen = methodDoc.indexOf('(');
// Annotations may have parameters, so make sure we are parsing the actual method parameters.
if (info.getAnnotations() != null) {
while (indexOfOpenParen != -1 && !isOpenParenForMethod(methodDoc, getElementName(), indexOfOpenParen)) {
indexOfOpenParen = methodDoc.indexOf('(', indexOfOpenParen + 1);
}
}
if (indexOfOpenParen != -1) {
final int indexOfClosingParen = methodDoc.indexOf(')', indexOfOpenParen);
if (indexOfClosingParen != -1) {
final char[] paramsSource =
CharOperation.replace(
methodDoc.substring(indexOfOpenParen + 1, indexOfClosingParen).toCharArray(),
" ".toCharArray(), //$NON-NLS-1$
new char[] {' '});
final char[][] params = splitParameters(paramsSource, paramCount);
final int paramsLength = params.length;
String[] names = new String[paramsLength];
for (int i = 0; i < paramsLength; i++) {
final char[] param = params[i];
int indexOfSpace = CharOperation.lastIndexOf(' ', param);
if (indexOfSpace != -1) {
names[i] = String.valueOf(param, indexOfSpace + 1, param.length - indexOfSpace -1);
} else {
names[i] = "arg" + i; //$NON-NLS-1$
}
}
return this.parameterNames = names;
}
}

Ready to test |
|
How do I test? Is it in one of the snapshot builds or release builds? |
|
Usually the Check for Updates menu command finds and installs the new version. |
|
Yes just saw that it built on Bamboo. |
|
Depending on the version of eclipse platform you have, you can get the latest build from one of these update sites:

Sorry for the late reply, other stuff came up. I was able to test it, so the expression |

The expression that triggers the exception this time is

Ready to re-test |

It's fixed, no more error :) |
Hi,
I'm getting an ArrayIndexOutOfBoundsException when using content assist in the Groovy editor. It seems to only happen on objects which have a certain extension method. The exception occurs only right after I press
.but not if I trigger content assist manually after typing the first letters.I'm using Eclipse 4.10.
