Re: Trouble with java on arm?

It appears there is.  A couple years ago vtk was failing to build on arm due
memory issues:

java.lang.OutOfMemoryError: Java heap space

see https://bugzilla.redhat.com/show_bug.cgi?id=1115920

To get around that we started specifying 2GB of heap space via:

JAVA_TOOL_OPTIONS=-Xmx2048m

Now with the updated java on aarch32 I'm getting:

  Error executing java -version: 1 Picked up JAVA_TOOL_OPTIONS: -Xmx2048m
  Error occurred during initialization of VM
  Could not reserve enough space for 2097152KB object heap

Are the armv7hl builders really that strapped for RAM, or is this a java bug
in the new build?

I'm trying a scratch build without this option to see if it works that way.
