In 3.2, I20060309-1000, the following is observed Select a blank line inside a Java class and do ctrl+space. In previous versions, this would propose a selection of methods that could be overridden from subclasses. Select a blank line inside a Java class, type 'get' and ctrl+space. In previous versions, this would propose get methods for local variables. Both cases now produce the error message: 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. The .log file contains the following: !ENTRY org.eclipse.jdt.ui 2 0 2006-03-14 10:51:37.629 !MESSAGE Content Assist: Disabling the "org.eclipse.jdt.ui.JavaNoTypeCompletionProposalComputer" (org.eclipse.jdt.ui.JavaNoTypeCompletionProposalComputer) extension to the "javaCompletionProposalComputer" extension point.

org.eclipse.core.launcher.Main.run(Main.java:977) at org.eclipse.core.launcher.Main.main(Main.java:952) The workbench stays upright, but subsequent completion requests do not complete successfully
Simplest test case to reproduce the bug public class X extends Y { //do ctrl+space here } class Y { public <U> void foo() {} }
Fixed and test added CompletionTest_1_5#test0269()
Verified using I20060328-0010 for 3.2M6
