Eclipse Memory Analyzer - Incompatible JVM

I have download Eclipse MAT and try to launch it on Windows.

Executing MemoryAnalyzer.exe display a popup Incompatible JVM with this message: Version 1.8.0_242 of the JVM is not suitable for this product. Version: 11 or greater is required.

As said in this doc, I have created a jre directory and copied an OpenJDK 16 which solves the issue.

But I don't find this solution very elegant. So I tried to add the -vm parameter in the MemoryAnalyzer.ini and also tried to create an eclipse.ini file as reference by the doc. It doesn't work !

Is there a way to configure the location of the JVM without copy it entirely in the mat/jre directory ?

  • NB 1: the documentation seems out of date. The MemoryAnalyzer.ini file exists whereas the doc references the eclipse.ini which is not present in the default installation.
  • NB 2: I don't want to change my JAVA_HOME just for this tool.
Solution

  • As said previously, one solution is to create a jre directory and copy a JDK in it.
