The instructions by peter budo worked perfectly   I had to add the jars under  Library Java JavaVirtualMachines JDK 1 7 0 Developer Preview jdk Contents Home jre lib  to my IntelliJ project libraries   Now it works like a charm   Note that I didn t need my IDE itself to run under 1 7  rather  I only needed to be able to compile and run against 1 7   I ll most likely continue to use Apple s JRE for running the IDE since it s probably more stable with respect to graphics routines  Swing  AWT    Like the OP  I was really keen on testing out the new NIO2 API   Looking good so far   Thanks  Peter

Java 9  10  11    Years ago  Apple joined the OpenJDK project  transferring their formerly proprietary macOS-specific JVM code as free-of-cost open-source  Apple ceased distribution of their own branded JVM JDK  relying on Oracle   s branded releases to include a version for macOS    Oracle has recently announced their intention to bring their Oracle-branded JVM release to feature parity with the OpenJDK project  with virtually the same code base  The company even donated their previously commercial tools  Flight Recorder  amp  Mission Control  to the OpenJDK project  This is part of the shift to a new rapid    release train    plan for predictably scheduled versioning of Java and OpenJDK  Notably  the periods for free-of-cost public updates is now shortened  See this 2017-09 announcement and this posting by Mark Reinhold     As a result of all this  macOS users of Java have a choice of vendors for a Java implementation  At this point  at least three sources are based on OpenJDK for macOS    Oracle releases of the JDK and JRE  with optional paid support  Azul Systems releasing    Zulu line of free-of-cost JVMs with optional paid support  Zing line of commercial JVMs with special features such as an alternate garbage-collector   OpenJDK source code  roll-your-own compilation  amp  installation  perhaps not practical for most of us     Meanwhile  IBM donated code for a JVM to the Eclipse Foundation  now housed in the OpenJ9 project  I wonder if they might support a macOS release as well  though it is too soon to tell   Personally  I am currently using the Zulu release of Java 10 0 1 from Azul on macOS High Sierra successfully with IntelliJ 2018 2 to produce Java-backed web apps with Vaadin   Installation Removal  Both Oracle and Azul provide utterly easy-to-use installers to install the JVM JDK on your Mac  Verify your installation by using the Terminal app  or equivalent  to type and run   java -version   You will find the Java installations in this folder at the root level of your drive  not in your home folder        Library Java JavaVirtualMachines   Each version from each vendor is found there  in a labeled nested folder  You can delete any installation simply by deleting the nested folder for that version and providing your system password when prompted   Java 8  You can download the Java Development Kit  JDK  for Java 8 for the supported versions of Mac OS X    Mountain Lion  10 8 3    Mavericks  10 9  Yosemite  10 10  El Capitan  10 11    Each version of JVM you install can be found here    Library Java JavaVirtualMachines   For more instructions and FAQ  see this Oracle Guide   Java 7  For every release of Java 7 since Update 4  a Mac version has been ready alongside the other platforms  Runs on Macs with 64-bit hardware on Lion  10 7 3    Mountain Lion  10 8 3    and Mavericks  10 9 x    Oracle announced the official release of the JDK for Java SE 7 Update 4 on Mac OS X  Lion   as of 2012-04-26  No more need for the tricks discussed on this page   Installation is simple per these instructions    Download from the usual place on the Oracle web site  Mount the DMG  Run the installer    This release has a few limitations  most notably the lack of support for Java Web Start and the Java Plugin for web browsers  That support is expected later this year   After installing  read the JDK for Mac ReadMe  Most importantly  if you want Java 7 to be the default  drag it to the top of the list in the Java Preferences app found in your Utilities folder   Mac OS X easily supports multiple JVMs simultaneously  Each is now found here    Library Java JavaVirtualMachines   Congratulations to the Apple  amp  Oracle teams for their achievement  This geek gets a thrill seeing Mac OS X listed as a  Certified System Configuration    Tip  To start Eclipse on a Mac with only Java 7 installed  open the alias file named eclipse rather than the file named Eclipse app   Java 6  Apple continues to supply an up-to-date implementation of Java 6 for all versions of Mac OS X up through Mountain Lion   If you do something that requires Java  such as type  java -version  in Terminal app  a dialog appears offering to install Java for you  If you accept  installation happens automatically similar to other  Software Updates  from Apple   You will find Java installed in this location  different than Java 7  amp  8    System Library Java JavaVirtualMachines   Java 6 has reached end-of-life with Oracle as of 2013-02  unless you have a commercial support agreement with Oracle   So you should be moving to Java 7 or 8   Testing New Version  In Terminal app  type java -version to verify which version is the current default   Deleting Old Versions  After installing a fresh version  you may want to visit the folder described above to delete old versions  Move the folder to the Trash  and provide your System password complete the move     By the way  Apple provides a mailing list for developers    technical issues related to Java on OS X

It s possible that you still need to add the JDK into Eclipse  STS   Just because the JDK is on the system doesn t mean Eclipse knows where to find it   Go to  Preferences   Java   Installed JREs  If there is not an entry for the 1 7 JDK  add it  You ll have to point Eclipse to where you installed your 1 7 JDK   If Eclipse can t find a JRE that is 1 7 compatible  I m guessing that it just uses your default JRE  and that s probably still pointing at Java 1 6  which would be causing your red squiggly lines
