Hi guys,

Thanks for the great tool!

I was trying to see if Eclipse MAT (1.7.0) works with java 9. I set the `-vm /usr/local/java/jdk9/bin/java` option in the MemoryAnalyzer.ini and it failed with a bunch of errors (attached). It gives a final message to resolve something in `config.ini` but it has way too much text to easily identify the fix. Would appreciate if someone can guide me here?

Thanks!

I haven't done much work on this so am not surprised there are problems, as stand alone Memory Analyzer is based on Eclipse 4.5 (Mars).

Some things to try:

Use JDK 8 instead
Install Memory Analyzer into Eclipse 4.7.1a
See if https://wiki.eclipse.org/Configure_Eclipse_for_Java_9 offers any ideas

The latest nightly builds have an update to cope with the Java 9 String format in Java 9 heap dumps.
