Summary: High CPU usage after hibernate/suspend and wake up Windows
Key: NETBEANS-2214
URL: https://issues.apache.org/jira/browse/NETBEANS-2214
Project: NetBeans
Issue Type: Bug
Affects Versions: 10.0
Environment: Windows 7
Java 8 u181
Reporter: Danton Estevam Pinto
Attachments: jstack_-l_PID.txt
After hibernate/suspend and wake up Windows with Netbeans running on it,
Netbeans starts a high CPU usage.
After Windows wake up, by analysing Thread tab of the Netbenas process on
Process Explorer, I see one threads remaining in infinite loop.
It seems there is a workaround like reported here:
