Is it possible you installed a newer Java, and put it on the PATH temporarily, and the restart wiped the PATH change?
Frage
My Java project is failing to start with the error below. This only started happening after I restarted my computer. What does this error mean?
Unrecognized VM option ' ExplicitGCInvokesConcurrentAndUnloadsClasses'
Could not create the Java virtual machine.
Any insight into what might be causing this error would be appreciated.
