Description Rainer Klute CLA 2016-08-08 05:34:46 EDT 
Under certain (and unclear) circumstances JDT does not find even a single JRE, i.e. the list of installed JREs is empty (Window → Preferences → Java → Installed JREs).

However, since Eclipse has been started successfully, at least one JRE is necessarily installed somewhere and should be included in the list.

Anything in the error log that would give us some hint?
Comment 2 Noopur Gupta CLA 2016-08-08 06:23:43 EDT 
Can you reproduce it with a new workspace?
Comment 3 Jan Peter Stotz CLA 2017-10-10 04:20:13 EDT 
May be this bug is Java 9 related? On my system (Windows 64bit, 64Bit Oracle Java9 JDK installed) Java 9 JREs are not detected.
Comment 4 Sarika Sinha CLA 2017-10-11 00:28:55 EDT 
Can you check the value in -
<Workspace>\.metadata\.plugins\org.eclipse.jdt.launching\.install.xml

And do you have any value for "java.home" set in System property ?

Strange, I thought I already had installed 4.7.1a however the download package has now changed. I installed the new version and now the Java 9 JREs are correctly found.
