Thanks Pavel and JJ's reply very much!
Surely, Jersery 2 depends on guava 14.0.1.
If the ony two modules depend on guava, I want to continue to give my
viewpoints,
1) The ways that Jersey 2 and Weld depend on guava are different.
weld-osgi-bundle.jar embeds guava as inner class, instead, Jersey 2
directly depends on guava in pom.xml.
BTW: for weld-osgi-bundle 2.0.3.Final, it embeds guava 13.0.1.
2) based on 1), while Weld tries to load guava related classes, it will
not find guava from glassfish/modules, and it will use inner guava.
However, while jersery tries to load guava related classes, it will
import classes of guava bundle from glassfish/modules. Deeply, while
glassfish was started, guava bundle will be in resolved state,
...
106|Installed | 1|GMS Module (4.0.1.b02)
107|Active | 1|GMS Bootstrap Module (4.0.1.b02)
108|Resolved | 1|Guava: Google Core Libraries for Java (14.0.0)
109|Resolved | 1|GlassFish High Availability APIs and SPI (3.1.8)
...
So, I suggest that if possible, whether jersery can also embed guava as
inner class and remove guava bundle from glassfish/modules in order to
improve starting performance?
Thanks
