Hello, I have been looking into tuning the garbage collector for solr. I found this entry on the lucene wiki that seems to be out of date.
The bug referenced is reported as resolved now. Could someone validate whether it is safe to use G1 garbage collection with lucene? "Do not, under any circumstances, run Lucene with the G1 garbage collector. Lucene's test suite fails with the G1 garbage collector on a regular basis, including bugs that cause index corruption. There is no person on this planet that seems to understand such bugs (see https://bugs.openjdk.java.net/browse/JDK-8038348, open for over a year), so don't count on the situation changing soon. This information is not out of date, and don't think that the next oracle java release will fix the situation." https://wiki.apache.org/lucene-java/JavaBugs
