You are correct - the full error message was: Exception occurred while setting up store modules. Attempting to close things down. class org.neo4j.io.pagecache.impl.SingleFilePageSwapper (in unnamed module @0x6166e06f) cannot access class sun.nio.ch.FileChannelImpl (in module java.base) because module java.base does not export sun.nio.ch to unnamed module @0x6166e06f java.lang.IllegalAccessError: class org.neo4j.io.pagecache.impl.SingleFilePageSwapper (in unnamed module @0x6166e06f) cannot access class sun.nio.ch.FileChannelImpl (in module java.base) because module java.base does not export sun.nio.ch to unnamed module @0x6166e06f (with a stack trace of course) Is there documentation on how to properly use the -XaddExports? Is it something like: -XaddExports:jdk.compiler/com.sun.tools.javac.api=ALL-UNNAMED > > >> Dagger fails due to the @Generated: >> NoClassDefFoundError: javax/annotation/Generated >> >> : >> >> For the Dagger case, I know it is accepting the '-addmods' argument, >> because it gives an error if I use '-J-addmods'.

It is the Google version of the Dagger apt processor. I did see that suggestion in one of the bugreports. With the -J-addmods, it complains about the option not existing (it doesn't with -addmods). With the -Jjava.annotations.common, it complains that the module can't be found. Without the -J it just fails to find the annotation. > > > -Alan >
