Description

Memory leak in XNIO on Server is ssl is used. This issue is valid only on HPUX platform.

This issue was find during ~~JBEAP-11888~~ verification. This issue occurs only if workaround for ~~JBEAP-11859~~, ~~JBEAP-13545~~ and ~~JBEAP-13547~~ is used. ~~JBEAP-11859~~ issue is present in EAP since EAP 7.1.0.ER1.

Steps to reproduce

configure https (one-way or two-way ssl)
ignore errors related with ~~JBEAP-11859~~, ~~JBEAP-13545~~ and ~~JBEAP-13547~~

do this in loop:

ModelControllerClientConfiguration config = new ModelControllerClientConfiguration.Builder()
        .setProtocol(server.getManagementProtocol())
        .setHostName("127.0.0.1")
        .setPort(server.getManagementPort())
        .setConnectionTimeout(timeout)
        .build();
ModelControllerClient c = ModelControllerClient.Factory.create(config);
DefaultOperationRequestBuilder builder = new DefaultOperationRequestBuilder();
builder.setOperationName(org.jboss.as.cli.Util.READ_ATTRIBUTE);
builder.addProperty(org.jboss.as.cli.Util.NAME, "server-state");
ModelNode result = c.execute(builder.buildRequest());

Exception on server:
