This may or may not be a problem, but we need to check this out carefully.
“In Java 1.6.0_21, the company field was changed from ‘Sun Microsystems, Inc’ to ‘Oracle.’ Apparently not the best idea, because some applications depend on that field to identify the virtual machine. All Eclipse versions since 3.3 (released 2007) until and including the recent Helios release (2010) have been reported to crash with an OutOfMemoryError due to this change. This is particularly funny since the update is deployed through automatic update and suddenly applications cease to work.”
We probably need to check how DrJava behaves, too.
