Created attachment 151100 [details] stacktrace
By process of elimination, the following file org.apache.lucene.search.spans.SpanMultiTermQueryWrapper is the class that causes the error. Lucerne version is 4.10.2 By just changing the jdk from 7 to 8 for the project (lucent core) causes the java.lang.AssertionError error to be raised (seen in the notifications area of nb) The nb and OS X 10.10 was a fresh install in the last week. The source file has not been modified, the character set is UTF-8. The whole project compile of under jdk7. A number of classes in the package had the spanner symbol, they all compiled ok, with the exception of the one mentioned. File opens in textwrangler without any visible problems. Aimee
Same problem after switching from even 6 to 8 I think. The class giving the AssertionError has the following class definition: @Entity public class ReportEntryElement <Type extends AbstractReportEntryElementType> implements ReportPart, Serializable{} Removing the extends makes the AssertionError disappear. I changed the jdk version of netbeans to 8_45. The file compiles, so it seems to be a problem in the parser of netbeans?
I reverted everything back to java 7_71 and it works. Netbeans is still running java 8_45. Does this mean there is an error in the java jdk implementation? Is there more infer I can provide to help you fix the problem? I would like to move to jdk 8. If this is not a netbeans problem I would like to submit a jdk bug report.
I also encountered this issue using NB 8.0.2, JDK 8 u45, and Windows 7. The error can be reproduced with the following: interface A { void someMethod(); // [M] } abstract class B implements A { void someMethod(int arg) {} // [M'] <-- overloads A.someMethod() } class C { static <X extends B> callX() { X instanceOfX = null; System.out.println(instanceOfX.someMethod()); // yes, this wouldn't run but we're interested in the parsing error here. } } ------------------ Using an interface [A] method [M] as an argument to another method where: - the class on which [M] is called [B] is defined as a generic <X extends B> - B is abstract - B contains a method [M'] that overloads [M]
