Cause

The default Java version was Java 11. When I checked the Java version used by default, It was Java 11 as shown below.

Check the JDK used by default

$ java --version
openjdk 11.0.1 2018-10-16
OpenJDK Runtime Environment 18.9 (build 11.0.1+13)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.1+13, mixed mode)

Solution

As a premise, AptanaStudio (or eclipse) uses Java at startup. If it is Java8, it will start normally, so specify the JDK version when starting Aptana Studio directly.

1. Check the installed JDK

You can check the currently installed JDK with the following command.

Check installed JDK

$　/usr/libexec/java_home -V
Matching Java Virtual Machines (2):
    11.0.1, x86_64:	"OpenJDK 11.0.1"	/Library/Java/JavaVirtualMachines/openjdk-11.0.1.jdk/Contents/Home
    1.8.0_181, x86_64:	"Java SE 8"	/Library/Java/JavaVirtualMachines/jdk1.8.0_181.jdk/Contents/Home

2. Specify Java 8 as the JDK when starting Aptana Studio

Info.plist exists in AptanaStudio.app, so edit that file.

xml:/Applications/AptanaStudio.app/Contents/Info.plist

<key>Eclipse</key>
  <array>
    <!-- to use a specific Java version (instead of the platform's default) uncomment one of the following options,
         or add a VM found via $/usr/libexec/java_home -V
      <string>-vm</string><string>/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Commands/java</string>-->
      <string>-vm</string><string>/Library/Java/JavaVirtualMachines/jdk1.8.0_181.jdk/Contents/Home/bin/java</string>
      <string>-keyring</string>
      <string>~/.eclipse_keyring</string>
  </array>

Edit the argument of -vm as above. (It should be commented out at first) The specified value may be specified by referring to the path confirmed in "1. Confirmation of installed JDK" above.

You can now start Aptana Studio.
