Thanks for feedback and the workaround, Vladimir. The credits for finding the bug and reproducing it should go to Robert Muir and Uwe Schindler, I'm merely a messenger, but I had a feeling you'd be interested :)

Hello everyone, I am an Apache Lucene developer, we've been running tests with Java 1.7 and this came up: http://bugs.sun.com/bugdatabase/viewbug.do?bugid=7070134 Porter stemmer is pretty widely used for shallow NLP, not only in Lucene. It'd be interesting to hear from jit gurus what's causing this (the problem does not occur in 1.6). Thanks in advance, Dawid
