These tests were excluded from JCK upon condition the error message was fixed (i.e. test reports "current configuration allows 5000 maxOccurs etc..."). So the same fix should be integrated to 6u10
As it was requested by JCK team, I explain why I submitted this CR. During investigation of this issue in 6u4 we came to agreement that these tests should be excluded, but java shouldn't report OOM but valid error message. JDK 6u4 was fixed and reports misconfiguration error on these tests. Unfortunately corresponding fix, it seems, was not integrated in 6u10. So I submitted this CR to track this issue.
