JDK 9: XXtra Command Line Options

In my last blog entry on JDK 9 compatibility, I included a list of the command line options that had been removed between JDK 8 and JDK 9. For this blog, I thought I’d do the inverse and look at the new command-line options available in JDK 9. I’m going to limit things to the

JDK 9: Pitfalls For The Unwary

  JDK 9 is in the final phases of development, heading towards release on September 21st.

Is An Agile Java Standard Possible?

  This week we had one of the three face-to-face meetings that the JCP executive committee (EC) has each year. This is only my second meeting of this format; despite my long history with Java it’s interesting to see the way things work from this perspective. Since the minutes of the meeting have not yet
