[jira] [Commented] (NETBEANS-963) java.lang.AssertionError:
Debugger lock taken in AWT Event Queue!
[ https://issues.apache.org/jira/browse/NETBEANS-963?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17032089#comment-17032089 ]
Arunava Sinha commented on NETBEANS-963:
----------------------------------------
Env:
Java: 13-ea; Java HotSpot(TM) 64-Bit Server VM 13-ea+25
Runtime: Java(TM) SE Runtime Environment 13-ea+25
System: Linux version 4.1.12-124.27.1.el7uek.x86_64 running on amd64; UTF-8; en_US (nb)
I tried debugging below code in release113 branch build
String s = "heelo Worlddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd";
Integer key = 10;
String value = "value";
HashMap<Integer,String> map = new HashMap<Integer,String>();
map.put(key,value);
System.out.print(s);
Now in variable window, I was able to click on ... button and see the value of both map and s variable
Please let me know step to reproduce the issue

> Key: NETBEANS-963
> URL: https://issues.apache.org/jira/browse/NETBEANS-963
> Project: NetBeans
> Issue Type: Bug
> Components: debugger - Java
> Affects Versions: 9.0
> Environment: Linux; Release Build 316
> Reporter: Peter Nabbefeld
> Assignee: ARUNAVA SINHA
> Priority: Critical
> Fix For: 9.0

> When I've selected the "String Value" column in Variables view of the Java debugger, the following exception is thrown even if I just move the cursor over the string value.
> This does only happen for object values; primitive values do not seem to be affected.
> Probably it's related to tooltips, as those are shown for primitive values, while object values throw an exception.
> As this makes it impossible to show and review large strings and thus makes debugging harder, I've set the status to "Blocker".
