Also ensure that you are using a file system that supports ACL. In case there are any issues while starting JMC with user permissions, then start JMC as an administrator. Ensure that the hsperfdata_username directory is present in the Windows $TEMP directory (for example, C:\Users\user_name\AppData\Local\Temp\hsperfdata_username) and is writable by the user.See: JDK 11 Installation Instructions or JDK 8 Installation Instructions as applicable. Ensure you install JDK 8 for JMC 8.0 and JMC 8.0.1, and JDK 11 or later for JMC 8.1.0 onwards.However, JMC 8 supports Java Management Console (JMX) monitoring and Java Flight Recorder (JFR) profiling of JVMs (JDK 7u40 and later) on any supported platform. JDK Mission Control (JMC) 8.0 and 8.0.1 starts with Oracle JDK 8 (64-bit), and from JMC 8.1.0 onwards it requires Oracle JDK 11 and later.
