[9] RFR: 8049314: javax/net/ssl/templates/SSLSocketSSLEngineTemplate.java fails intermittently with "Unexpected EOF" message

[Artem Smotrakov]

Hello,

Please review this patch for SSLSocketSSLEngineTemplate.java test.

The test fails intermittently with "Unexpected EOF" error. Please see 
Brad's comment which explains the issue

https://bugs.openjdk.java.net/browse/JDK-8049314?focusedCommentId=13519136&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13519136

Calling compact() method before continuing (as Brad suggested) seems to 
solve the issue. The patch also updates the test to use a 
try-with-resource block while reading keystores.

sun/security/ssl/SSLEngineImpl/SSLEngineBadBufferArrayAccess.java test 
doesn't seems to be affected because it always calls compact() after flip().
