System Workbench for STM32

The problem was not JAVA1.8 that was installed but the JAVA JDK.
JAVA was uodated to version 1.8 but the JAVA JDK was still version 1.6. With the terminal command:

$ /usr/libexec/java_home -V

it shows the following:

Matching Java Virtual Machines (2):
1.6.0_65-b14-468, x86_64: "Java SE 6" /Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
1.6.0_65-b14-468, i386: "Java SE 6" /Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

After updating the JDK to version 1.8 from the JAVA websit:

Eclipse works!

Thanks for the information,
