Erick Erickson commented on LUCENE-4362:
----------------------------------------
Robert:
You're right in that a number of tabs are introduced into the generated files,
I'll leave those for another day.
So, I didn't change any of the .java files that had a corresponding .jj or
.jflex file, but I did try to run the "ant jflex" target in
lucene/analysis/common after taking out all the tabs in the .jj or .jflex
files. I figure that that's worth doing separate from fixing the injected tabs.
Unfortunately I keep getting
jflex-UAX29URLEmailTokenizer:
[jflex]
[jflex] Error: JFlex has run out of memory. Please try increasing the
maximum JVM heap size
[jflex]
. What's the magic to increase the JVM heap? Or should I just not bother?
I tried setting ANT_OPTS JAVA_OPTS, changing the jflex script in
<jflex_home>/jflex/bin to $JAVA -Xmx2G JFlex.Main $@, and I keep getting the
same error. Which means there's an incredibly simple way to do this that I
don't know about......
Any hints?
