Jang commented on WW-4994:
--------------------------
Hi Lukasz
We are using Java 1.5.
However, in the previous version (2.3.34), we completed the upgrade using Java
1.5.
Has 2.3.35 been modified to use only Java 1.6?
We can not upgrade the Java version right away.
Can I temporarily fix the problem?
Thanks.
