I have an error that says some package (e.g., com.sun.misc)isn't accessible but it's on my classpath, how do I fix this?
In most cases, people get this error by accessing the Base64 class from the Sun VM. We generally don't recommend using the Base64 class from the VM because your bundle will be tired to only VMs that have that specific class. However, if this isn't an issue, you can get around the access restriction error by adding an access rule to your system library to make the package accessible. You can do this on the Libraries tab of the Java Build Path project properties. Add an Accessible rule for com/sun/misc/*
Also, in most cases, this package needs to be visible during runtime. To have a package visible during runtime, you will need to add the org.osgi.framework.system.packages.extra system property. For example:
org.osgi.framework.system.packages.extra=com.sun.misc,com.sun.java.swing.plaf.windows
