I get the following error when using content assist on this test case: Content Assist: Disabling the "org.eclipse.jdt.ui.JavaNoTypeCompletionProposalComputer" (org.eclipse.jdt.ui.JavaNoTypeCompletionProposalComputer) extension to the "javaCompletionProposalComputer" extension point. Reason: The extension has thrown a runtime exception. Here is the test case: import java.util.HashMap; public class Test1 { <T> HashMap } To reproduce, place the cursor after HashMap, invoke Content Assist (CTRL+SPACE), and choose the first suggestion. There is an exception thrown in 3.1.1 as well, but the error message is different.
Oops, forgot to say I'm using version 3.2M4 (I20051215-1506) with GTK2.
We will yet change the way we react to a failure in a completion proposal computer. The underlying exception is in jdt-core, see below; moving to jdt-core. === java.lang.ArrayStoreException at java.lang.System.arraycopy(Native Method) at

Fixed and test added GenericsCompletionParserTest#test0205() CompletionParser must override consumeTypeParameter1() and not consumeTypeParameters1()
Verified for 3.2 M5 using build I20060215-0010.
