54173 - Secure JNI env is not available until applet is loaded

Status: VERIFIED FIXED

(Core Graveyard :: Java: OJI, defect, P3)

Description

[Michail Romanov]

From Bugzilla Helper:
User-Agent: Mozilla/4.74 [en] (Windows NT 5.0; U)
BuildID:    2000091213 (Netscape_20000922_BRANCH CVS branch)

  Impossible to get JNI env from JVMManager neither
via jvmMgr->CreateProxyJNI(outProxyEnv) nor via jvmMgr->GetProxyJNI(outProxyEnv) 
until any applet is loaded. Both methods return NS_OK and NULL as outProxyEnv.
  However when outProxyEnv is got (after applet is loaded in
some page) attempt to make any JNI call freezes Mozilla.

Reproducible: Always
Steps to Reproduce: Run e.g. JNIEnv_GetBooleanField_5 OJI API test.

Actual Results:  Important OJI module functionality is unanailable.

Expected Results:  JNI env must be accessible from OJI module if OJI plugin is 
presented.

Waiting on receiving hardware to test on linux.

At Eric Krock's request, I've taken a stopgap measure until my real linux
hardware arrives: vmware.  Let's hope it works well.

Waiting for my infernally slow VMware linux build to complete.

Can you, Michail, provide more details of how to reproduce the problem? I tried
the test page that called JNIEnv_GetBooleanField_5, and got the result of
correct value returned. Thanks.

Tested this out wiht FCS build of Java Plugin.
the test was able to return a valid JNIEnv (Had to use a workaround for 
FindClass by Setting XBootclasspath). 
the tests did go thru'.

the bug has been fixed in th eJava Plugin
