A fatal error has been detected by the Java Runtime Environment: EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x00007ff8387e54c2, pid=21860, tid=7748 about openjdk HOT 1 CLOSED

Thank you for the report!
It looks like you are using a modified version of Minecraft. The following was detected in your crash report:

--launchTarget forgeclient
--fml.forgeVersion

Please try the following:

• Update your graphics drivers, see this Minecraft Help Center article, section "Update your Video Card Drivers";
  often Minecraft crashes are caused by outdated graphics drivers
• Try disabling the mods you have installed one by one until you find the mod causing the crash, then report the crash to the mod author
• If you are using a third-party launcher, try the official launcher instead

If none of the above helped, and you are still experiencing the crash with the official launcher and without any mods installed, please submit this issue over at the Mojang bug tracker. Please search for existing reports first; in case you do not find any, create a new report and let us know about the issue number here (e.g. MC-123456).
The Mojang team will take the first look. If an OpenJDK bug is identified, the Mojang team will contact the Microsoft Build of OpenJDK team to address the issue.
