Launching client has encountered a problem while deploying on Windows 10 ------------------------------------------------------------------------ Key: JBIDE-20044 URL: https://issues.jboss.org/browse/JBIDE-20044 Project: Tools (JBoss Tools) Issue Type: Bug Components: server Affects Versions: 4.3.0.Beta1 Reporter: Martin Malina Labels: Windows10 Fix For: 4.3.0.Beta2 Attachments: launching-client.png Today I started some testing on Windows 10. I installed JBDS 9.0.0.Beta1 with embedded EAP 6.4. When I tried to run a html5 project on the server, I got this error during the deployment: Problem occurred 'Launching client' has encountered a problem. An internal error occurred during: "Launching client" java.lang.NullPointerException !launching-client.png! In the Error view the only extra detail I get is this: {code}java.lang.NullPointerException at org.eclipse.core.internal.jobs.Worker.run(Worker.java:71){code} The project will still deploy. I verified exactly the same thing on Windows 7 32-bit and both were a virtual machine via VirtualBox on my machine. But for some reason the Windows 10 instance is running a bit slower, so this *might* be connected to timing. Also, if I deploy the app through Server -> Add or Remove, then it works fine. I understand that you will probably not get your hands on Windows 10.
