annot00701.html, annot01602m3.html and intf01004m1.html hang while compiling (b102)

JCK : JCK6.0 b32, JCK1.5a b11
J2SE : FAIL - mustang b102, since b91 PASS b90
Platform[s] : FAIL - seems to be all
switch/Mode : FAIL - fail with defaut keys

Three tests:

lang/ANNOT/annot007/annot00701/annot00701.html
lang/ANNOT/annot016/annot01602m3/annot01602m3.html
lang/INTF/intf010/intf01004m1/intf01004m1.html

Are wrongly determined as "passed" by JDK 1.6. Tests expect java classses to be rejected due to wrong syntax. Unfortunately real situation is that compiler shows error and then starts to collect system resources then throw error:

The system is out of resources.

We found this error while performing test with JCK 1.5a b11 and JDK 6.0 compiler with "-target 1.5". Tests were rejected as hung.

jdk 1.5 u9 compiler rejects these tests correctly.

jtr's attached.
