In my application, Envers failed to create a AUD table for an entity that included a large string property (mapped to a TEXT column in MySQL). So the following class failed to generate a AUD table:
{code}
package com.redhat.topicindex.entity;

private Integer helpId;
private String tableColId;
private String helpText;
public Help() {
}
public Help(String tableColId, String helpText) {
this.tableColId = tableColId;
this.helpText = helpText;
}
@Id
@GeneratedValue(strategy = IDENTITY)
@Column(name = "HelpID", unique = true, nullable = false)
public Integer getHelpId() {
return this.helpId;
}
public void setHelpId(Integer helpId) {
this.helpId = helpId;
}
@Column(name = "TableColID", length = 512)
@Length(max = 512)
public String getTableColId() {
return this.tableColId;
}
public void setTableColId(String tableColId) {
this.tableColId = tableColId;
}
@Column(name = "HelpText", length = 65535)
@Length(max = 65535)
public String getHelpText() {
return this.helpText;
}
public void setHelpText(String helpText) {
this.helpText = helpText;
}
}
{code}
Once the HelpText property was modified, the AUD table was created:
