I want to step through some classes of the Oracle JDK implementation using the Eclipse debugger.
So I downloaded the current JDK from Oracle (jdk1.8.0_77), installed Eclipse via the Windows installer and wrote a simple HelloWorld class.
However, when using the 'Step into' debugging command steps over the lines that invocate JDK methods like System.out.println.
I configured Eclipse to use the JRE that is contained within the JDK instead of the standard JRE and ensured that step filters are neither set in the preferences nor applied in the debug view as explained in these answers:
How can I step into a core java class method in Eclipse?
So why doesn't 'Step into (F5)' step into the source?
Thanks in advance!
