http://vmlens.com/articles/java-math-BigDecimal-toString-is-not-threadsafe/ JVM wtf

I didn't get this from the article -- is this the official sun/oracle jvm, or is this some other jvm ?

The comments seem to make the claim that it’s an ARM JVM and that this is a JVM bug, in that the actual code for BigDecimal can’t throw the reported NPE if the Java Memory Model spec is respected

Does anybody have a soft talk or podcast to recommend, suitable for watching/listening past midnight? 🙂
