org.eclipse.core.launcher.Main.main(Main.java:668) Steps to reproduce: 1) Check out org.eclipse.update.core from CVS HEAD 2) Open org.eclipse.update.configuration.LocalSystemInfo.java 3) Go to line 52: * @see LocalSystemInfo<CODE ASSIST HERE>#getType(File) You should get the log in the error log view.
I am seeing this one too. It seems to depend on the conent of the javadoc. Here is a sample that reproduces the error (content assist at |): /** * {@link Boolean| * some text <b>bold<i>both</i></b> */ public void foo(String s) { } if you remove any of the words from the second line it works. Most strange.
Fixed and test added CompletionParserTest2#test0148 GenericCompletionCompletionParserTest#test0185() CompletionParser#attachOrphanCompletionNode() must not be call if completion node is already attached.
Second test is GenericsCompletionParserTest#test0185(). Verified in I20050214
