A \fIversion range\fR is made up of a version string followed by a plus sign (\f3+\fR) to designate this version or later, or a part of a version string followed by an asterisk (\f3*\fR) to designate any version string with a matching prefix\&. Version strings and ranges can be combined using a space for a logical \fIOR\fR combination, or an ampersand (\f3&\fR) for a logical \fIAND\fR combination of two version strings/ranges\&. For example, if running the class or JAR file requires either JRE 6u13 (1\&.6\&.0_13), or any JRE 6 starting from 6u10 (1\&.6\&.0_10), specify the following:

 The young generation region of the heap is used for new objects\&. GC is performed in this region more often than in other regions\&. If the size for the young generation is too small, then a lot of minor garbage collections will be performed\&.
